SYMPTOMS

When you attempt to install a printer in Windows NT, you may receive one of the following error messages:

  • There are no print processors
  • Print Processor is unknown

CAUSE

This behavior can occur if all of the following conditions exist:

  • No print processor is specified in the Windows NT registry.
  • The print processor file (Winprint.dll) is missing or corrupt.

RESOLUTION

To resolve this problem, follow these steps:

  1. Verify that the Winprint.dll file exists in the following folder:

    %SystemRoot%\system32\spool\prtprocs\w32x86

    If the Winprint.dll file is missing, use the following command to expand the Winprint.dl_ file on your Windows NT Setup CD-ROM or Setup disks to Winprint.dll in the above folder:

    expand x:\i386\winprint.dl_ c:\winnt\system32\spool\prtprocs\w32x86\winprint.dll

    where x: is the drive letter of your CD-ROM drive.
  2. Verify that the print processor is configured correctly in the Windows NT registry. To do so, follow these steps:

    WARNING: Using Registry Editor incorrectly can cause serious, system- wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

    a. Locate the following key in the Windows NT registry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print \Environments\Windows NT x86\Print Processors\winprint

    If the Winprint key is not present, create it by clicking Add Key on the Edit menu. If Winprint.dll is not specified as the Driver value in the Winprint key, click Add Value on the Edit menu to create the Driver value using the following settings:

    Driver:REG_SZ:winprint.dll

    NOTE: It may be necessary to restart the computer after making these changes.
