New Technique Could Trace Documents By Printer

An anonymous reader submits "From this article at Purdue News, 'Researchers at Purdue University have developed a method that will enable authorities to trace documents to specific printers, a technique law-enforcement agencies could use to investigate counterfeiting, forgeries and homeland security matters.' The neat thing is that they are exploiting the characteristics of the print process itself to identify the printer." <update> One of the folks e-mailed me to say that the HP LaserJet 9000dn was one of the big ones tested with.

Ok, you are so full of shit you stink from here.

your printers are incapable of printing less than it's maximum dpi. and no laser or inkjet let alone a dye-sublimation printer is capable of microscopic printing.

nice of you to make up crap, but let's at least make it slightly believeable.

show me a proof before you start throwing about lies as truth. Espically when it goes against physics and mechanical capabilities.
