When you hit "print" in Office, Adobe, or any other program, does it take 30-45 seconds or more to come up with the printer selection screen? Chances are, an offline printer is affecting the performance of your printing.

To solve this issue:

In XP:

1.  Go to Printers and Faxes
2. Highlight any "offline" or "unable to connect" printers
3. Hit the Delete key, or right click and select Delete

In Windows 7:

1.  Go to Devices and Printers
2. Highlight any "offline" or "unable to connect" printers
3. Hit the Delete key, or right click and select Delete

This should solve the issue. If not, please let me know so I can provide further fixes!
