Printer: HP deskjet 840C OS: Windows XP
PRinter stopped printing thought I was out of ink. Replaced ink cartridge and still does not print. Have primed cartrdige two or three times, have updated drivers, gone through XP printing troubleshooting steps, gone through HP's online troubleshooting steps. Still printing blank pages. Ink comes out of cartridge blots on white page. Any ideas of why not printing all of a sudden?
