One thing I’m concerned about is recording equipment leaving identifiable information without us knowing about it.
minus-squareArdens@lemmy.mllinkfedilinkarrow-up0·2 months agoIt’s not specific to USA… They do it everywhere - with color-printers. Don’t know if they do it with B/W printers. They claim it’s to track people who try to print money, but if it were, then they wouldn’t really do it on laser printers too… If you print a photo on a regular paper, and then shine an UV-light on it, you can see it. It’s mostly small yellow dots.
minus-squareमुक्त@lemmy.mllinkfedilinkarrow-up0·2 months agoThey use yellow ink for that in colour printers.
minus-squareमुक्त@lemmy.mllinkfedilinkarrow-up0·2 months agoYou wrote more, much; but left this to inference. I highlighted one bit: yellow.
minus-squarepirat@lemmy.worldlinkfedilinkarrow-up0·2 months agoI just occured to me that could be the reason for when a color printer wont even let you print, say, pure black text, even though it only has emptied some of the colored ink, but still has plenty of black ink left to do the job…
minus-squaregrey_maniac@lemmy.calinkfedilinkarrow-up0·2 months agoThere is software you can use that adds all the other dot patterns to essentially anonymize your printer.
minus-squareArdens@lemmy.mllinkfedilinkarrow-up0·2 months agoI know - but it’s good that you added that to what I wrote. :-)

Did I not write that?
