Color Laser Printers Tracking Everything You Print 795

It's not new, but it's getting noticed: Jordan writes "Yahoo! News is reporting that several printer manufacturers are now and have been for some time embedding (nearly) invisible serial numbers in every document you print with their color laser printers, allowing law enforcement to track any such document back to the printer which printed it. The technology, ostensibly created to track down money counterfeiters, was created by Xerox about 20 years ago. A Xerox researcher says that the number-embedding chip lies 'way in the machine, right near the laser' and that 'standard mischief won't get you around it.'"

    Printer manufacturers have been doing this for a long time.

    Epson inkjet printers, for example, supposedly embed serial codes using droplets of yellow ink in black regions. The serial numbers can't be seen by the human eye, but they apparently can be detected somehow.

    Right.. However, the Serial number will tell the feds right where the printer was sold, then they check the cash register computer to find out exactly when it was sold.

    After a quick check of the surveillance camera's, they've got your face (or the person who bought it, if its you) and are coming to raid your house.

    tinfoil hat time: go to a different city, buy your printer with cash and never send in the warranty card. since it'll never be registered under your name; any documents you print, at best can be traced back to the original store.

    Nobody prints with green ink. That's a primary color in RGB, and surely nobody prints in RGB. The printing primary colors are CYMK: Cyan, Yellow, Magenta, and blacK. No green.

    Yes, you can come to return an item without a reciept and as long as you have a picture ID you can get your money back if you know someone/fight with them/are really cute.

    But this assumes that you gave them the proper information in the first place. You don't have to provide them any of that information, but you do forfit your ability to return junk without a reciept and get cash back.

    Good points, but it is fairly trivial to be 100% anonymous.

    Don't buy new printers, buy used. Don't buy used from eBay or similar, buy used from swap meets, garage sales, etc. Pay cash. Use a firewall. Use open source software instead of the proprietary drivers to print.

    When you install your OS, use all bogus information when filling things out like your user name, host name, etc. Don't use anything that could be traced back to you, like naming your computers after your kids or your dog or whatever. Best case, name your computers "host1" or "cpu1" or something similar.

    Don't use retail gear to do your work...buy used, just like the printer. A Pentium 300 laptop is essentially free on the open market. Do a secure wipe on the hard drive, install OpenBSD, hook up your printer and use a generic driver (no fancy fonts, etc) and you are good to go.

    Buy a 802.11 card on the open market, also with cash. Use a free WiFi hotspot to publish...never go into the place with the hotspot, sit outside (less chance of cameras, etc). Use privacy services, anonymizers, Publius servers, etc to publish your work.

    If you need to make copies, go to any college campus or big city, pick someone off the street, and pay 10 or 20 dollars for them to go in and make the copies for you.

    100% anonymity can be done without too much trouble, as long as you pay attention and stay organized. It never ceases to amaze me that they find people who write worms and other malware...in this day and age, releasing malware with 100% anonymity is trivial.

    Neat. I'm holding an old $5 from 1995 next to a new $5 from 2003. The old $5 has text as the entire outer line, but the newer one only has it for about 1cm of the middle line (there are now three lines) near the name Lincoln.

    When you install the driver, significant information is sent back to the printer vendor's website.

    What kind of information do you think is sent back to them?

    Unless you can print this using Linux CUPS driver at 4800x4800 (which I've yet to see one).

    Wrong. Only seven states (Alabama, Florid, Iowa, Kentucky, MIssissippi, Nebraska and Virginia) permanently deprive felons of the right to vote, and even these allow felons to petition to regain that right. Such petitions are often granted. Most other states deny felons the right to vote only while they are imprisoned, or on parole. Maine, Utah and Vermont allow felons to vote even while they're still in prison.

    In CMYK, printing a color on top of another color makes things darker. Yellow dots would not show up on the black ink - they would actually darken things up. If you knew exactly what you were looking for, where you were looking for it at, and what a yellow/black overprint looks like, you *might* see it. Obviously, if it is printing on the black, the agencies in question know whee to look and what they're looking for.

    Anyone in the business of repairing any full color laser printer, photo copier etc, is usually told of this in certification class. At least it is when I go to school on these. On our full color copiers & printers, they specifically tell us that if you attempt to make a color copy of any "money" it will lock up, requiring a phone call to unlock it, and a visit from someone in a black suit and dark glasses LOL. We make a blank copy, and get out a high power loop, and you can see the faint yellow microdots that contain the information. A few years ago, some idiot bought a full color copier, and started on one end of the country, driving to the other end passing off phony money. When the treasury agents got the copies, they looked up the serial number and traced it back to the dealer who was more than happy to supply the information, and they got the guys vehicle info (he wasn't smart enough to fudge his name, etc when he bought it) and they caught up with him, with the machine in his van, and loads of fake bills. Personally, I don't care if they put serial numbers on this, you can't see them anyway, plus, if you are STUPID enough to forge documents, you deserve what you get!

    Nobody prints with green ink.

    Nobody at home, maybe. Commercial printers print with all kinds of ink. If a pamphlet, coupon, or package only needs a few colors in block graphics (no complex shadings), it's more practical to use exactly the colors of ink needed than to uce CYM. Color alignment is simpler, and you use less ink.

    Q&D example off my shelves: Dove soap. The package is has only four colors, two for text, one for solid graphics, and one shaded. The printer used four colors: black, deep bluish-green, light bluish-green, and gold.

    The hardback editions of The Neverending Story were also printed with a bluish-green ink.

    Or think of green-lined ledger pages; you think a printer is going to go to the trouble to line up a cyan and a yellow run when he can do one green run and be done with it?

    So it's entirely plausible that an ink manufacturer or a commercial printer had to abandon a particular variety of green ink as being too close to one of the government's protected shades.

    Here's two:

    with some choices of drink, if you have long and
    skinny arms.

    2. Put two pieces of 2-inch clear packing tape
    together, so that the sticky side is in. On one
    edge, include 1/8 inch of a bill. So about 98% of
    the bill is not taped. Give yourself about two
    feet of tape hanging off the bill. Soon after the
    bill goes in, yank it out.

    Note: only do this if you have permission from

    Depends on your definition of freakin' expensive.

    A froogle search for color laser printer [google.com] pulls up hits under $500. That's roughly a two days wages for me, certainly not freakin' expensive by my definition.

    I imagine most people could afford one if they really wanted it. A few months of saving up (hell if you're a smoker, quitting would get you the cash pretty quick), or a simple credit card purchase with making the minimum payments would easily do it for most I think.

    HP's installation software for the 4 in 1 laserjet 3015 demands you shut down your fire wall and anti-virus software to install the driver. Can anyone say "SPYWARE!"???
    When I took HP's indian tech support weenie to task for this, he tried to insist that there was no spyware (acting all nervous and flustered that I'd make such an insinuation).
    I said, "Dude, I can see the packets flowing out my ethernet port as the driver is installing, don't try to lie to me."
    He replies (in that oh so Indian way of speaking), "Fine, go ahead, jou won't be able to use dee scanner, but jou ken install just dee driver files." (huffing in exasperation)....

    Uh, am I the only one that noticed that this article only refers to color laser printers? And only from a few manufacturers at that.

    Obvious solution: use an inkjet or a dye-sub. Both inkjets and dye-sub printers are better for printing in color anyway, unless what you need is top speed at the expense of color accuracy and resolution (which is not likely even for a counterfeiter).

    If you're talking copiers, I don't know. Are most copiers laser these days? Still, it seems implausible that any counterfeiter would be using a consumer copying machine to commit his or her crime (simply because the results would be pretty obviously awful), so I'm not sure why this technology would even be necessary.

    But the obvious solution for yourself in that case is to do what I do to make my copies - buy a flatbed scanner that has a "copy" button on it and use your inkjet printer for the output. I get much better quality that way than using any copy machine I've ever tried anyway, and it's really not much more inconvenient either. My scanner, PC, and printer all have to be on and running, but it's literally a one-button process just like it is on a regular copy machine. If my PC is off, the time it takes to boot is not really much longer (if any) than the time it takes a standard copy machine to "warm up" from a cold start anyway.

    For the moment, this seems pretty easy to get around, if what the article says is really accurate. Because what it says is that certain brands of color laser printers use this technology. So, the solution is to not use those brands, or to not use a color laser printer. Seems pretty simple. May not stay that way forever, but it doesn't seem like it's time quite yet to start hoarding pro-level inkjets before they're outlawed.

    OK, let me get this straight..... 20 billionths of a second..... In order to fit 4 bits (assuming 4 bit words as laser commands, best-case scenario, and assuming serial) in as the laser is firing..... you would need 160GHz bandwidth, plus the overhead of the actual "data" to get through. I don't think ribbon cable is quite capable of this inside a printer.

    Combined with the "millimeter sized" dots, I think we have an extreme exaggeration of the facts.... I don't think we can trust the "about every inch" on the page either. More investigation is required.

    I'm curious to know how you arrived at a universal human right of anonymity

    Please refer to:

    TALLEY v. CALIFORNIA, 362 U.S. 60 (1960) [findlaw.com]

    McIntyre v. Ohio Elections Comm'n (93-986), 514 U.S. 334 (1995) [cornell.edu]

    Very relevant is the quote from McIntyre:

    "The decision in favor of anonymity may be motivated by fear of economic or official retaliation, by concern about social ostracism, or merely by a desire to preserve as much of one's privacy as possible. ... Anonymity is a shield from the tyranny of the majority. It thus exemplifies the purpose behind the Bill of Rights, and of the First Amendment in particular: to protect unpopular individuals from retaliation -- and their ideas from suppression -- at the hand of an intolerant society."

    While one can reasonably question anonymity as a "universal" right applicable in all times under all conditions, these times should be the exception rather than the rule with the burden falling on those who say that the restriction should apply rather than on those who say not.

    I guess all this rebate crap really is a government conspiricy.

    Hardly any of us bother to send in any product registration crap. If you have the receipt you've covered for warranty issues.

    But, entice you with a bogus $50 rebate ( which you may or may not get 6-8 weeks later ) and many will gladly give their home address, email address, phone number. Cash the rebate check and you give up your banking info too ( all that stuff they print on the back of the check when you deposit it.)

    If you plan on doing naughty things with your laser printer you'll have to pay cash (not at Costco ) and blow off the rebate.

    I sometimes use some of these printers (xerox's 2060, 5252, 6060's) at work. The dots are straight yellow toner, much smaller than 1 mm, but are large enough to see in bright light if you have excellent eyesight. They are easily visible under a printer's glass, or a decent magnifying glass.
    The pattern repeats itself across the entire page, whitespace and all. As yellow is the last colour laid on the paper I would expect that they can easily detect the pattern in any area that doesn't have solid yellow.
    Interesting - I just checked a couple of prints and it is all across the colour one, but not on the one run in black and white mode even though it uses the same print engine.
