So my landlord got a new Dell color laser printer, and I was curious about the “yellow dot tracking” that new printers use. So I printed a page and scanned it at 600dpi.
Ok, nothing crazy going on there, as one would expect, so I looked closer.
Hrrm, look there, I see some yellow dots. Let’s strip away all the colors but blue so they get darker.
Well, will you look at that. Sure enough the page is covered in little dots in a specific pattern.
I guess it’s all totally true, color laser printers are adding information to printed pages to show where they came from.
I can’t say that makes me overly happy.
