Windows: No Local Ports Are Available for Printers

Problem:
When adding a new printer, the list of available ports is empty, and you cannot add any printer port.


Cause:
The driver for the local port moniter (Localspl.dll) may have been replaced by a 3rd-party local port moniter.


Solution:
1. Start -> Run
2. Type in regedit, and press ENTER
3. Goto

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\ Local Port

4. Modify Driver to localspl.dll
5. Restart the Print Spooler service
