SYMPTOMS

When you attempt to print to a Hewlett-Packard (HP) 4000-series printer connected to printer port LPT1, you may receive one of the following error messages:

Error writing to LPT1: For <document name> Access denied Error writing to LPT1: For <document name> The requested resource is in use The handle is invalid.

Or, the print job may become stuck in the spooler

CAUSE

This behavior can occur when you install the HP 4000-series printer drivers included with the HP Complete Printing System for Windows from Hewlett-Packard

NOTE: This behavior can occur when you try to print to printers other than HP4000-series printers if HP Complete Printing System for Windows is installed on the computer

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 issue, rename the Hpdcmon.dll file in the %SytemRoot%\Sstem32 folder To do so, type the following line at a command prompt:

ren c:\%SytemRoot%\Sstem32\Hpdcmon.dll Hpdcmon.xxx

If this does not resolve the problem, follow these steps:

1 Start Registry Editor (Regedt32.exe)

2 Go to the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Monitors\HP Laserjet 5 Language Monit

NOTE: The HP Language Monitor key may vary in name depending on which HP driver is installed

NOTE: Do not delete the PJL Language Monitor key

3 On the Edit menu, click Delete, and then quit Registry Editor

4 Click Start, point to Settings, and then click Control Panel

5 Double-click Add/Remove Programs, and then click the Install/Uninstall tab If HP Printing System appears in the list of installed programs, click Add/Remove
