One thing I’m concerned about is recording equipment leaving identifiable information without us knowing about it.
minus-squaregrandel@lemmy.mllinkfedilinkEnglisharrow-up7arrow-down1·edit-215 days agoIve never noticed this or heard that printers do that. Is this maybe specific to the USA? Edit: TIL, thank you!
minus-squareArdens@lemmy.mllinkfedilinkarrow-up21·15 days 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-squaregrey_maniac@lemmy.calinkfedilinkarrow-up9·15 days agoThere is software you can use that adds all the other dot patterns to essentially anonymize your printer.
minus-squareArdens@lemmy.mllinkfedilinkarrow-up2·15 days agoI know - but it’s good that you added that to what I wrote. :-)

Did I not write that?
