I recently upgraded my BIOS, with much back and forth with esupport, and the flash went smoothly with no apparent problems. Some of my previous problems seem to have reduced. Fantastic . I kept getting a found new hardware pop=up for my already installed Canon Multipass C755, I am running Windows XP SP2. The printer worked fine. I checked the hardware and found an LPT1.4 port. My lpt1 port was still there. The found new hardware wizard was just annoying. So, finally today I thought I would remove the printer and reinstall, hoping that that would place it in the correct spot. Well, now I can't reinstall the printer. The current disk is not compatible with XP, but I have an update and a patch for xp2. When I try to start the printer installer it does nothing. The hourglass icon flashes for a few minutes and then nothing happens. I've checked the event logs and nothing seems to be pinpointing the issue. I've tried totally removing all the bits of the old software right down to removing the registry entries, without any luck. I've tried plugging and unplugging the printer from both the computer and the power. I am at my whit's end. The printer is connected via a parrallel port, just not a LPT1.4 port. I removed the key for the LPT1.4 port from the registry, but when I turned the computer back on, it was back. I would appreciate any suggestions. Thank you.
