    Printers are the text book examples of why device manufacturing shouldn’t be left to big companies. You have tracking dots, spyware infestation, subscription for ink/toners, reporting of the cartridge as empty when you still have much left in it, refusal to print when unused color cartridges are empty, intentional bricking if 3rd party cartridges or ink is used, and utterly crappy firmware in general.

    Inkjets require precision manufacturing. But assembling it or other types from components should be possible - like how desktops, mechanical keyboards, etc can be. We really need to ditch filthy mass market printers because DIY printers will be much better than anything they offer.

      I’m pretty sure this measure was requested either by the government or some big three letter agency.

      I doubt that, if all printers were manufactured by a government monopoly, you wouldn’t have this shit baked in. It would probably be way worse

    It’s how Reality Winner got real fucked.

    via Wikiedpia:

    Both journalists and security experts have suggested that The Intercept’s handling of the reporting, which included publishing the documents unredacted and including the printer tracking dots, was used to identify Winner as the leaker. In October 2020, The Intercept’s co-founding editor Glenn Greenwald wrote that Winner had sent her documents to The Intercept’s New York newsroom with no request that any specific journalist work on them. He called her exposure a “deeply embarrassing newsroom failure” resulting from “speed and recklessness” for which he was publicly blamed “despite having no role in it.” He said editor-in-chief Betsy Reed “oversaw, edited and controlled that story.” An internal review conducted by The Intercept into its handling of the document provided by Winner found that its “practices fell short of the standards to which we hold ourselves”.

          And they will argue that whistleblowing is actually a crime, because, uhm, it’s, uhm, yeah it’s illegal! And if it’s illegal to be a good citizen, then this is totally warranted and no scandal at all, because only bad people do illegal things!

            Actual opinion some people hold: “We need to make end-to-end encryption illegal to stop criminals”

            How on earth is that meant to work? Criminals are criminals. They don’t care whether or not it’s illegal. At this point, just declare all crime illegal and call it a day. At least that won’t be a huge infringement on honest people’s privacy and security.

      Interesting. I remember reading a news article before 2017 stating that printers used to do this, but the practice has since ended because someone was able to prove they were doing it in the mid-2000s. At the time, I saw some people on Reddit claiming they just switched to a new, harder to detect method, and everyone was saying they were conspiracy theorists.

      Those dots are practically invisible if you have the printed copy, they’re not going to be visible at all in a photography. Printers and their network leave a lot to logs behind, pretty sure they just check up the printed files of their network, found the document and who send the printer order and done.

          It’s cheaper and easier to look at the print logs. Most business computer and printer solutions tie every print to a user and log at least the name of every document printed

          The hidden code is for court cases where they wish to prove which machine made the print, they’re not very good for identifying which user printed something in a multi user environment

    Wikipedia has a good article on it, including photos of what the marks look like. They’re practically invisible to the naked eye, getting them to show up usually requires additional steps like taking high quality scans and running them through some color filters, or using a UV light.

    From the EFF coverage of it, it sounds like every laser printer probably prints these marks now. I’m not sure if inkjets or other printer types do or not.

      I find that a large number of conspiracy theories are asking the right questions, just not providing the right answers. Does big tech want to control our minds with 5G towers and microchips hidden in covid vaccines? Probably not. Does big tech want to control our minds with social media and invasive advertising? Absolutely. Is the world controlled by a secret society of lizard people? Probably not. Is the world controlled by a not-so-secret society of billionaires and politicians? To a large extent. Even those awful racist or bigoted conspiracy theories start to sound somewhat palpable palatable if you filter out the racist or bigoted part. Do Jews make life for the rest of us miserable by controlling the economy? No. But replace “Jews” with “the owning class”, and suddenly it kind of makes sense.

      EDIT: Is the government putting chemicals in the water that turn frogs gay? No. Are corporations putting chemicals in water bottles that turn frogs into hermaphrodites? Literally yes

        As someone who has worked in IT communications, nobody deploying 5G is doing anything differently than for 4G/LTE/3G/2G or even coax/DSL/fiber/whatever. The only functional difference is that it’s faster. It may operate with newer tech, faster chips, different frequency bands, different modulation techniques, etc… But at the end of the day, it’s just a means to get data from here to there. Nothing more.

        Also, the government (or “the man” or “them” or whatever), already have an almost universal method to track every living person in the country. You willingly carry this tracker with you at all times; to work, to the park, to friends and family locations, etc… If you haven’t guessed yet, it’s a cellphone.

        A big part of increasing the network speed on commercial wireless networks (cellular provider networks) is reducing cell size, aka, the amount of space each radio covers, and just increasing the number of cells (radios) serving an area. They know exactly which cell(s) your phone is connected to, where those cells are, which direction the antennas are facing and how far you are away from it (by signal strength, or rssi). This can be triangulated with other antennas that can “hear” the same signal, and all of their metrics (location, direction, distance), and that information can be quickly collected and cross referenced into a very accurate location.

        This can be done without any software on your device, and very likely without having a valid service plan. As long as you’re in range and the cellular radio is on, “they” already know where you are. And you carry your phone with the radio online at all times, willingly. Pretty much once you get to have your own phone as a teenager, they know where you are and “they” have been able to track you since.

        Having apps like Facebook and whatever that get your location information from the network and the app relays it to Facebook (or whatever corporate entity), is the equivalent for the corporate overlords. You just need to invite them in by having the application installed, and it can report that data to them.

        Most do this entirely willingly and could not give any fewer shits about it.

        This is not speculation, this is part of the technical capabilities of the systems. Whether or not the government or any legal entity is using the information for this purpose is up for debate, but the fact that it can be done isn’t in question. There are entire companies dedicated to building solutions which correlate connection data to geolocate connected devices with a high degree of accuracy.

        A nontrivial part of the reason these systems exist is for e911, which can relay GPS information to emergency services. A system which does not work very well for most counties because their 911 systems are too old and underfunded. If it works correctly, your precise location and altitude (to determine if you’re on the ground floor or not), can be accessed by emergency services in the event that it is required. Usually those features are only accessible or activated if you actually dial 911 (or your country’s equivalent emergency number), but they’re built out and exist regardless of if you need/use it. This was made a requirement by the government since your physical address bound to the number you are calling from, is not necessarily where you are when you make the call. In the olden days of landlines, every phone number would come up with the service address when you called 911. Since the service address was the only location you could use that line from, that worked. Now that we’re almost entirely mobile, it’s not useful anymore, so this system was devised. Then the government promptly denied sufficient funding to 911 systems to implement their end of the system, while mandating that carriers set it up.

        It’s stupid. But I digress.

        The fact is, you are being tracked. It’s being done for your own good (re: emergency services), but it’s very easily abused by those who can access it. People like government agencies.

        Whether they’re abusing it or not, that’s a question you’ll have to figure out for yourself.

          different frequency bands

          Actual conspiracy theory: Very small fish tend to die a few days after being exposed to electromagnetic metal detectors. Fewer die if you hold them above the metal detectors. This is an observable phenomenon you can try at your own expense. While I don’t think 5G is a significant enough increase in energy density to cause you to die, there is a good chance it’s enough to introduce destabilization in homeostasis due to body warming. Especially if you live within 100 meters of a tower. Babies tend to be fussier sleepers when sleeping very near routers or baby monitors using a meager 2.4, 5, or 6 GHz, attempt experimentation at risk of the children.

          Whether they’re abusing it or not, that’s a question you’ll have to figure out for yourself.

          Not a conspiracy theory: Snowden proved they are. Everyone in a 5 Eyes country is stuck having their private moments exposed at any given moment for any reason.

            It’s a well known scientific fact that higher frequency waves carry more energy. For larger mammals, such as humans, these differences are trivial for the most part. Unless you’re standing in a location which is exposed to high amplitude and high frequency EM waves, the danger is generally nil. By high frequency, I’m talking about pretty much anything over ~10Mhz, and for high amplitude, I’m talking about power levels at or above 100W. Putting 100+W of power through an antenna is extremely rare, and due to things like attenuation, free space path loss, reflections, refractions, etc, unless you’re basically standing directly next to an antenna, in its transmission path, you’re fine. Bluntly, this is why cellular towers are set up the way they are. Usually an antenna mast will have a relatively small support pillar of some sort, usually a cylindrical “pipe” shape, or a set of support beams in an overlapping “x” shape, which narrows as it goes up. At the top it usually flares out for where the antennas are mounted, so if you climb up the mast, you end up behind the “business end” of the antennas; aka, they’re pointed away from you. This means that the vast majority of energy being produced is directed away from where you are. For everyone else, being on the ground or even in a nearby building, you’re too far away to be exposed to significant signal amplitude. We can it EIRP in the industry, or “estimated isotopically radiated power”. The EIRP drops off quickly in the first few meters after the antenna, as the signal expands outwards towards the service area; so even being within 15m is generally safe.

            EM waves can be dangerous, specifically in the extremely high bands; IMO, this is what scares people. Extreme high band EM is dangerous at most power levels. These extreme high bands are capable of causing damage at the cellular level, possibly causing your DNA to break down. These are referred to as “ionising”. The bands that people most commonly know that are ionising, includes UV and X-ray. High band UV 2 and UV 3 are in this range, and x-rays are too. They’re all EM waves and they are extremely dangerous. These are all emitted by our sun, and mostly blocked by ozone. Some small levels of UV 3 might get through (hello skin cancer). What I want to point out is that these are all at, or above hundreds of terahertz in frequency. UV bands start around 800Thz. 80,000 times higher than 10Ghz. It goes up from there.

            Light, which is also an EM wave is between 400-800Thz, and it’s widely considered harmless. Yet, common folks tend to start to freak out about EM above ~6 GHz because of a lack of understanding. 8Ghz is more than 100,000 times lower than the low band of UV (which is non-ionising). Any EM wave with sufficiently high transmission power is strong enough to cause damage, for most frequencies below 400Thz (aka, below visible light) would need to be significantly higher than what we normally use. For context, transmission power at the antenna for broadcast radio (eg FM radio stations), is usually around 100kW maximum per antenna system. These transmitters can be legally and safely placed in urban areas provided adequate separation between the antenna and the public, usually 30-40 meters. To contrast this, the broadcast power of WiFi at 2.4Ghz is usually set at or around 100mW (0.1W), with a maximum output of around 1W (legally at least). To further this example, microwave ovens use 2.45Ghz frequency EM to heat your food. This is usually combined with a very well insulated cage to prevent that energy from escaping, which both protects you and your home from being cooked, and also directs the energy towards the item being heated, improving efficiency. Most modern microwaves can emit around 1000W (or 1kW) of power. 2.45Ghz is, however, special, in the way that it directly interacts with water. This specific frequency can excite water on a molecular level to create heat. I won’t go much further into it than that. So it’s unique in the interaction it has. Something something resonant frequencies something something… Look into it if you’re curious. The point is that your 2.4 GHz WiFi is 1000-10000 times less powerful than your microwave. Other frequencies do not have the same effect on water or other molecules. If your microwave ended up emitting 3Ghz instead of 2.45ghz, you would have a microwave that consumes a lot of power, which doesn’t do anything useful.

            I mention this to point out that the amount of power needed to affect something in favorable conditions is generally at or above ~800W of transmission power, in the equivalent of an EM “mirror” box. Consumer goods generally will never transmit above 1W. Even at 0.1W you can usually saturate your house, your yard, and your neighbors yard… At least enough to “see” the signal.

            “5G” and “6G” mobile/cellular technologies operate in the gigantic band between 900MHz and 400THz (often on the lower side of that very broad range), well below the level of ionizing EM, and at power levels well below what would be dangerous. The largest 5G arrays run with power levels around 120W. Which is less than 1/8th the power of your microwave, and at a maximum of 40Ghz, well below ionising.

            Scientifically speaking, 5G mobile carrier antennas are less dangerous than walking under a 1000W flood light, which people do without hesitation, or even a thought given to any possible danger from the exposure to the ~600Thz EM being emitted by the floodlight.

            Bluntly speaking, it’s a stupid argument to be afraid of 5G for the transmissions themselves. You will not be harmed by them.

                That… Is definitely not recommended.

                I only have a fairly basic grasp of physics and biology, and from what I know, the microwaves will heat up the water inside your cells… Specifically the 2.45Ghz emitted by the magnetron in a microwave “oven”. It will easily penetrate your flesh and heat you up from the inside out… Like, on a cellular level. The water inside your cells can very easily and quickly boil, causing the cell to explode… Especially when exposed to ~1000W of 2.45GHz EM energy. It’s non-ionising so the effects will be limited by the amount of exposure, and limited exposure won’t cause much damage. Your body will very easily heal, since you lose cells all the time. Prolonged exposure will kill you.

                Also, activating a nearly 1kW magnetron in an open environment will have devistating effects on anything operating in the same frequency band, and likely anything on resonant frequencies, which will likely get you in trouble with the FCC (or local regulatory body), which can include aircraft, military operations, emergency services… It’s a long list. If they use radios as part of their normal operation, a powerful and unregulated transmission like this can basically jam their system making any legitimate broadcasts unintelligible. This can obviously put lives at risk.

                With that said: do not do this.

                I’m licensed to operate radio equipment in amateur radio bands up to 190W EIRP (if I recall correctly), and I don’t think I’ve ever used anything more powerful than 50W, I don’t own anything more powerful than 25W, and anything with the antenna attached to the radio (like a handheld radio) that I own doesn’t exceed 10W, most are 5W. For me, if I was using anything over 50W, I’d want a band pass filter on my antenna feed line to eliminate spurious emissions on resonant frequencies just to be extra careful.

                That all being said, since the damage from this guy has already been done, I wouldn’t expect any further issues for him. I’m sure his biological systems have fully recovered from the exposure, and I don’t expect it to resurface again. If it was higher frequency (ionising radiation) then he would probably already have died, and even if he didn’t, he would be in for a lifetime of hurt, but yeah, 2.45Ghz is relatively safe by comparison.

                Just to note, above x-rays are all the radioactive emissions that come from stuff like nuclear materials. Which is why they’re called “radioactive” … They’re actively emitting radio (EM) waves. Usually well into the petahertz and exahertz, while ionising radiation starts in the very high terahertz range.

                1Ehz = 1,000Phz = 1,000,000 Thz = 1,000,000,000 GHz (For clarity)

              Truly, thank you so much for responding. I love learning from experts.

              This is usually combined with a very well insulated cage to prevent that energy from escaping

              Faraday cage. Please. I’m a fool, not an imbecile. And to be clear, I’m well-aware of ionizing radiation bands.

              However, my concerns lie in extended exposure. I’ll relate this to analog. Regardless of frequency, sound as quiet as 70 decibels can cause hearing loss after extended exposure. In the territory of 24 hours and longer, mind you. This is as quiet as, say, a hearty conversation, or a washing machine.

              And this is a dual inverted sliding scale. Hearing loss zones:

              • | XXdB | Duration before hearing loss. |
              • | 70dB | 24h | As quiet as a clothes washer can cause hearing loss. Really.
              • | 75dB | 8h |
              • | 80dB | 2h |
              • | 90dB | 1h |
              • | 95dB | 50m |
              • | 100dB | 15m |
              • | 105dB | <5m |
              • | 110dB | <2m |
              • | 120+dB | Instantaneous |

              I’d like to know where the scales for EM radiation amplitudes are. I’ve read a few studies but most of them focus on bursts or separated exposures. Very few of them observe sustained continuous exposure.

              Also, I’m aware sound and radiation are not apples to apples, but my point of relating energy input and exposure duration is the same. If you ask anyone if 70 dB is safe, everyone will tell you, “Yes. Of course.” Which is not correct. Even 60 dB can do you further harm, if your ears have not healed from damage sustained immediately prior.

              Some small levels of UV 3 might get through (hello skin cancer).

              Now you’re getting into much more familiar territory. UV-A, the lowest band of UV, at UV 1 is entirely capable of causing sun-burns. It just depends on exposure time and pigmentation. Any sunburn has the potential to cause cancer. The more intense the burn and larger the affected area, the higher the chance more cells mutate, the higher your chance one of those cells becomes an unstable cancer cell, the higher the chance one of those cells becomes stable, and the higher chance for metastasis… From non-ionising low flux UV-A. Possible, but unlikely. Though increasingly likely as duration increases.

              These transmitters can be legally and safely placed in urban areas provided adequate separation between the antenna and the public, usually 30-40 meters.

              The EIRP drops off quickly in the first few meters after the antenna, as the signal expands outwards towards the service area; so even being within 15m is generally safe.

              Inverse square, I’m familiar. And now we’re cooking with fire. Let’s elide frequency for a moment, pretending it’s irrelevant in the same way mechanical waves’ frequencies are.

              Let’s assume 30-40 meters for 100KW antenna and 15 meters for ~20W macro cell is instantaneous minor damage. With each meter you distance yourself, the concentration of wattage decreases. What do you suppose the limit of energy density is for immediate damage when in direct contact? What do you suppose is the limit of wattage for sustained direct exposure on scale of 24 hours. That is, the equivalent of 70dB for intensity. What about sustained exposure for several years?

              I don’t fear the effects it will have. After all, death will come to us all at some point. However, that doesn’t mean I’ll be reckless with the time I have left.

              Also, I just started studying to get my Ham and haven’t quite wrapped my brain around a lot of the implications, so your input is very much appreciated. Thanks.

          They’re also refusing to accept evidence they don’t like. Like there are two examples that spring to mind: the fact that the earth is an oblate spheroid and the fact that trans people existing is a natural phenomenon in our species. For the former there are mountains of evidence and anyone who’s spent any time near an ocean knows it’s true. It’s just not what your eyes or feet notice. They’re questioning their assumptions but they came to a conclusion and accept all flimsy evidence rather than more solid evidence that it’s not true. And they never ask why. For what fucking reason would people spend billions fabricating this conspiracy?

          For the latter these people see a group of people who violate social norms in a way that they aren’t comfortable with anc do ask why. But they then answer it maliciously without evidence and repeatedly reject evidence and in the process eventually find themselves conspiring to hurt that group preemptively. Similar thinking happens against Jewish folks.

          I applaud curiosity, I didn’t get enough sleep last night because of my own, and I’ve done a science before. But conspiracy theorists give their curiosity to dark parts of their psyche and let it run wild

            Bluntly, I don’t think they’re doing it because they’re Jewish, it’s because they’re rich and entitled. But not all rich people are Jewish and not all Jewish people are rich, so it’s likely that they’re wrong.

    The EFF has some info about the practice - https://www.eff.org/pages/list-printers-which-do-or-do-not-display-tracking-dots.

    I imagine there are ways and means of obfuscating / anonymizing the dots such as blocking the printer from emitting them (e.g. an empty yellow cartridge that the printer perceives as full), modifying the firmware, using a burner printer, or using a mono laser jet.

    As a side issue, most modern bank notes have a bunch of yellow circles integrated into the design on each side. They look random but they’re in a recognisable pattern called a constellation that enables devices like copiers / scanners to recognize when people are trying to copy money or other financial instruments like checks.

    It’s weird that when it comes to security companies are like “we got too many important things to be doing, like adding this quarters new shiny feature, we don’t have time to encrypt user data”.

    You would think that when it comes to adding obscure tracking codes companies would be like “we don’t care what people print, it’s not our problem, we aren’t going to bother with tracking watermarks”. But, no, every company has tracking watermarks while cutting every other corner possible.

    I mean, half the companies out there are barely able to get their software to work, meanwhile printer companies have this robust watermark system that never fails. I don’t understand these priorities.

Finally I print to PDF (Even if it is already PDF) and email that or use one of those fax apps if fax is absolutely required.

            If it is paid app with lots subscriptions, most likely it is safe (or as safe as government). The biggest problem with those if somebody else steals your login info from their system. I do not believe they hunt or store faxes themselves if you delete the document after sending.

              Just take a photo with a trusted regular camera app and then enhance it with imagemagick. I have this script, works like a charm: convert INPUT_IMAGE.jpg -colorspace gray \( +clone -blur 15,15 \) -compose Divide_Src -composite -normalize -threshold 80% OUTPUT_IMAGE.jpg. Pretty sure you can also specify multiple input images, and imagemagick can merge it into a PDF file. For joining a really large number of images into PDF files (e.g.scans of entire books), you can convert each image individually, and then pdunite them. So something like for i in *; do convert $i $i.pdf; done; pdfunite $(ls *.pdf | sort -n) output.pdf

              Apps are bloat. Reject modernity, embrace shell scripts.

                I agree.

                Does it count if one uses an LLM to help compose the shell script? I mean, I can and have written gnarly scripts by hand but it can take half an hour to work out a single line sometimes for a simple task versus 10 minutes describing it in plain language.

                  Of course it “counts”! Whatever gets the job done! I personally am pretty bad with writing shell scripts, so I often use LLMs as “pseudocode compilers”. Like, I literally give it an entire program in pseudocode, and most of the time it can “compile” it to BASH or posix shell pretty well. Maybe some people might argue that it’s better to just sit down and learn shell scripting yourself, but I would argue that just by looking at or tweaking LLM-generated scripts you’re already passively learning the basic syntax and conventions. Not to mention that you can ask it to explain parts of the code to you!

          An app isn’t going to fax the document, though, which is where I’d assume the $12 charge is really coming.

      I am always pissed off when someone sends me a document to print, sign, scan and send back. You are still missing your stupid fax machine, don’t you?

      I have no printer because it’s not worth the upkeep, so I have to walk down the street to a copy shop and print, sign, scan and send back my personal data there.

      Thank you, fax machine person.

        Is pasting in your signature digitally not an option? That’s what I’ve been doing all my life, but then again the area where I live is quite progressive in terms of technology.

        On a related note, someone should make an image filter that makes digital documents look like they’ve been scanned in. Would save a ton of paper and people’s time lol.

          Problem with that is that simply pasting your signature is in no way legally binding. Someone could crop your signature out of a random document and then sign a bunch of papers with it.

          With a paper copy you’re supposed to keep the hard copy (and so is the other party, that’s why you always sign in doubles).

          Hell even printing, signing and scanning is quite vague in terms of legal value… You’d have to actually send the original hard copies by mail to be 100% covered. (With a registered letter at that).

          Digital signing will supposedly make this whole process easier, but doing that digital signing can only be executed by a small amount of certified organisations. (As in everyone can digitally sign something with their own keys, but it won’t be legally recognized)

          Not a lawyer, just someone who tried to figure out how signing legal documents works to include it in an inhouse program at work

      I threw mine of the balcony when it refused to print again.

      I’m not even kidding. It felt amazing. (I did clean up the mess tho)

        I dismantled several cheap inkjet printers for parts. There are countless useful parts inside for my future DIY projects. 24-volt power supplies, several motors, pulleys, belts, hundreds of small bolts.

      Sometimes don’t have a choice, at least here in AU there are lots of government institutions that still only accept paper copies of certified documents either snail mailed or physically handed in

      Yes. I rarely print documents, but as a hobby arts and crafter, I do print of lot of stuff for my projects. Screw inkjets, but they do have a really high resolution in photo mode, which is the only reason I haven’t ditched my nightmare printer for a laser yet.

        and we go 20 miles in the snow both ways to touch said grass, because I had an onion on my belt which was the style at the time.

            Why are a giant laptop or a monitor the only options? I read recipes off my phone all the time! No fancy set up required, I just read it while I’m cooking! I still don’t see how any of this is related to your original statement about “touching grass” though

              Just need to scroll through 800 lines of garbage back story and hope they use the keep screen alive toggle! And it’s super easy scrolling with shit on your hands!

              Not everything is made better by a 6 inch screen.

      Halfway competent criminals know how to prevent it. But at the same time, I am simply against any and all non-consensual tracking.

      I have a similar stance on this as DRM.

        What do you mean by non-consensual? You agree to the terms when you use that printer? I agree that I don’t like either it nor DRM, but you have a reasonable ability to read first.

      It also can’t be used to track you if your printer is kept off the internet

    The K in CMYK is grey, not black. The other ink tones are added to make it appear black.

    Edit: It seems people don’t want to hear that. But sorry, that’s how CMYK works. Black is roughly C=75 M=68 Y=67 K=89 in most major colour profiles used for printing. When you tell your printer to print something black, it won’t use just Key (around 85-90% grey), and will apply normal CMYK blacks which use value from all 4 inks.

    It’s been like this for 120 years and is not a “big printer” conspiracy. If you don’t like this, don’t use a CMYK printer. It’s just going to print CMYK values with CMYK inks like you told it to and none of those inks is black.

      That’s not really the case (grey), but it’s what happens by default.

      The K does stand for blacK. The four are mixed to create a richer black than the black alone would provide - which conveniently looks better and uses more ink.

      The software and printer are more than capable of not using “rich black” outside of images, but even the solid black ink will look muted to people used to seeing the mud from all four colours in their 12 point Times New Roman.

      A sad state really that in 2024 we still have an ink racket.

      My color laser printer uses only K to print blacK. It takes four cartridges, and I’ve only had to replace the C, M, and Y cartridges once in the 15 years or so I’ve owned it, because I almost never print pages with color.

        It sounds like your printer has a true monochrome mode you can specify. Makes and models that are more user-hostile often use drivers that default to grayscale for non-color prints.
