After spending hours trawling forums and support areas, and trying all the solutions suggested, I'm at my wit's end. I'm running 10.6.6 on an iMac and all of a sudden my FujiXerox 203a printer was constantly reverting to offline. Up to this point it had performed flawlessly. Fuji advised deleting the printer, resetting the printing system, deleting cups.gz file, rebooting, then downloading and reinstalling the driver from their website, and adding the printer all over again. Problem is, I can't add the printer because the computer no longer presents it to me in the 'add printer' list. I've used system profiler to check the usb connection and it's showing the printer by name but 'add printer' just doesn't recognise it. Does anyone have any suggestions at all as to what I should try next?
