While your scanner is no longer actively supported by Canon, they still have updated
drivers for it on their European web site:
http://software.canon-europe.com/products/0000471.asp
The info on their web site says that it supports and works with XP, so there is nothing
inherent in either that will keep them from working together...fact is, they worked
before. My guess is that changing the method of connection on the fly is not supported
by the drivers, but that an uninstallation then a fresh installation reflecting the
current physical hookup should get it going again.
First, uninstall any Canon software currently on the computer, then physically disconnect
the scanner. Restart the computer.
Next, check the documentation to make sure the CORRECT cable is being used. IIRC,
those printer-bypass scanners did not use standard IEEE1284 cables when bypassing
a printer, but did use a standard cable when directly connected to the parallel port.
Also check to see if you need to enable/disable any specific settings for the parallel
port, either in the BIOS (ie, Bi-directional, EPP ECP) or within XP (ie, IRQ related).
After looking into all that and adjusting as required, download the current drivers
and then do the instalaltion as if this was the first time it was being installed.
Post back to let us know if it worked for you!
