One thing I’m concerned about is recording equipment leaving identifiable information without us knowing about it.
minus-squaregrandel@lemmy.mllinkfedilinkEnglisharrow-up4arrow-down2·edit-27 hours 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-up16·9 hours 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.
