SYMPTOMS

When you try to print to a Hewlett-Packard (HP) 4000 printer through the LPT1 or LPT2 port on a computer running Microsoft Windows NT Workstation 4.0 Service Pack 3 or Microsoft Windows NT Server 4.0, the print job may not be printed and you may receive the following error message:

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this behavior, delete the HP print monitor information values from the registry:

Using the Services tool in Control Panel, stop the Spooler service.
Start Registry Editor (Regedt32.exe), and then locate the following registry key:
```
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Monitors
					
```
Delete the HP Jet Admin value and the HP Language Monitor value.
Restart the computer.

NOTE: The Spooler service starts automatically when you restart the computer.
