Query: Worst POS printer I have ever seen

POS does not refer to "Point of Sale" in this case so use your immagination! After purchasing new, branded ink cartridges, TWICE, for this piece of crap, I continue to get an error message on the printers display "Print Cartridges....Refer to printer documentation". There are countless "solutions" to this problem from the HP website and help desk. None of wich work. To make matters worse there is a very annoying flashing yellow exclamation symbol that starts up as soon as you power on the printer.Help from HP is a joke, this printer has a firmware problem, that has never been fixed and apparently, HP has no intention of doing so. Do yoursrlf a favor, look into Canon or Epson, thier ink is less expensive and thier hardware does not suck. I gave it 1 star because Amazon doesn't let you rate 0 stars.
