Do people really buy printers new? I don't think I have ever bought a new printer. My friend bought a "broken" printer at a garage sale for $5, took it home, put new cartriges in it, aligned it, and has used it for at least a year.
Printers are something deadhead technophobes discard like used lightbulbs. I'd be surprised if 99.9999% of the tracking they do with these dots ever leads back to the current owner...
