After you upgrade to Windows XP, when you try to print a document you receive:

5. Close Device Manager and close System Properties.
To set the port for your printer:1. Use Control Panel / Printers and Faxes to right-click your printer and press Properties.
2. Select the Ports tab.
3. Clear the LPT1: box and check the LPT3: box.
4. Press OK.
