Well, I am back from Korea... I upgraded my iBook from X.1.5 to X.2.4 and did the same for my desktop. I have a Samsung laser printer that I had to reinstall on both and it worked fine. I have a Canon Ink Jet that I also had to reinstall. However, it reinstalled and worked fine on my desktop, but after repeated cleaning out of every file on the iBook related to it that I could find, and reinstalling it, the Print Center won't recognize any printer there before I install the drivers, and after I install the drivers, it will find the Canon, but then won't let me add it to my list of printers, saying that the drivers are not installed. Any suggestions?
