I bought a new printer(HP deskjet 990cse) and it worked fine for several days. PC case fan died and was just replaced. Once the system was reconnected to everything, wanted to print some output. I now get garbage.. Thought my parallel cable might have gone bad, so I replaced it... still getting garbage. go into device manager and the printer port shows that it is working fine. I get garbage if trying to print from a DOS prompt and if I boot to DOS. Can one run some kind of dianostics on the parallel port to determine if it is bad or not? If it is bad, what are my options?
