KharmaGirl said:If you use an ink jet printer, the print head is in the cartridge. so I"m not sure how that would be possible. If you are money concious and have your cartridges refilled, again it would be impossible. Same with refilled toners. Since tonly a fraction of printers have built in print heads, I can't see this being feasible at all. The ink comes out of a one time disposible cartridge that you can buy anywhere. If you print alot, don't let the cartridge start to dry up (those will "skip" a little bit) and do regulr print head cleanings you should be fine.
LOL Its not dots. Its the serial # that prints in yellow. Yellow on white is the least noticable. It doesnt matter what cartridge you use, this function is perfomed by the formatter board inside. The formatter tells the machine what to put on the paper. I dont believe inkjets use this but most color lasers do I believe.
Even with a SN, its not 100% possible to track the machine. If you go into Office Depot, buy a printer and pay cash, how does HP know who the machine went to? I sell office equipment and dont send back S/N to the OEMS nor do many other dealers
Take my word on this....
The phone thing is a trip though. I wouldnt have thought twice about talking to someone about things while my phone was in my pocket. But the truth is the only way this is going to happen is if you are already under investigation
