Title: Sellers: don't forget about your (color)printers!
Post by: k1ngk0ng on July 03, 2011, 11:02 pm
hey there!

it might be old news for most, but be aware of the fact that most modern _color printers_ add some sort of identification marks on printed pages which usually contain printer serial number and date/time of printing.

this information _could_ be used to track a printed label back to the person who printed the label.

brief info:
http://en.wikipedia.org/wiki/Printer_steganography

best is to use a black/white printer only imo. but even then I'd recommend to check the pages with a 200x magnifying glass.
