HP printers are the worst. Printers fail to print "Black" after a short peroid of time, two (2) months. HP support is zero help. It not an empty cartridge, its not a old cartridge, its not a dirty printer head IT IS a lousy printer!
I will make it a point to go to the printer section of every store I visit that sells printers and if I see someone even looking at an HP printer I will warn them not to buy HP!
