Windows XP Professional must not like the Hewlett-Packard OfficeJet R40 on it's parallel port. A day after setting up this printer/scanner, I had to manually change it from trying to use the DOT4 port and point it to LPT1 for printing. Even though printing and scanning were just fine when I first set it up. Now the silly thing is trying to access the scanner in a similar way. After becoming frustrated looking for LPTENUM information, I decided to just reinstall the devices.

• Power off the HP R40
• Open Device Manager and remove these three items:
• Reboot
• Power on the HP R40
• Open Device Manager
• Right click the computer name at the very top
• Click Scan for new hardware

Hopefully, everything will work again until WinXP gets restless.
