Since upgrading to Windows XP Professional the computer has problems between my printer (HP DeskJet 880C) and scanner (CanoScan FB320P). The scanner only operates if I have used the printer during the computer session. If I attempt to use the scanner after using the printer, the following message appears: ‘Parallel port may be used by another application: Error code 0x0060800’. This causes problems if I want to use the computer to scan and print documents (like a photocopier), as I must reboot the computer after each print-job so I can use the scanner. Interestingly enough, the printer works fine at all times. I have tried turning off the printer after the print-job, and installing the latest drivers for the scanner but these did not fix the problem. In the Canon Knowledge Base they suggested buying a USB cable and connecting the scanner to a USB port. Would this fix the problem? If all fails, I am inclined to replace both the printer and scanner, since they are quite old. Would you have any advice on good equipment for home-use? As I need to scan in book format, an “all in one” machine won’t do, since it only scans A4.
