I ordered from several other sellers and still had problems with my printer - no issues with the HP ink or order at all - everything worked great and to boot they included an envelope to put old cartridges in to recycle :)
I have 2 printers, a 2423e and a 3630. I bought the tri-color ink #63 and #64.. Cannot get either printer to work. All I get is the ink (orange) light flashing. Why won't they work?
