can't print at all...help

I'm working on a G4 running OS 9.2.2. Just recently, my computer has refused to print from any application. I just did a series of small upgrades from OS 9.1 to OS 9.2 to OS 9.2.2 and I'm guessing something happened during that process that screwed things up. Because other than that I can't imagine why every application would simply stop printing all together. I get messages like..."Cannot open the printer." and "Could not complete the print command because of program error"...and on and on. I've reinstalled all of the printer software and drivers. I've gone into the chooser multiple times and chosen the printer over and over again...the setup looks fine...I've restared a million times...Any ideas of what to do next?
