SYMPTOMS
========

When you use a third-party printer driver to print, no output is generated and
the server may stop responding (hang). When you print to a file, the resulting
file size is 0.

CAUSE
=====

This problem occurs because Windows NT Server 4.0, Terminal Server Edition does
not provide support for this type of extension.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows NT Server
4.0, Terminal Server Edition. For additional information, please see the
following article in the Microsoft Knowledge Base:

   Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT Server 4.0, Terminal
Server Edition. This problem was first corrected in Windows NT Server 4.0,
Terminal Server Edition, Service Pack 5.

MORE INFORMATION
================

User-mode printer drivers can be used for modification of the data to be
printed. Other uses may be for additional security checks for submitting a print
job.

You can find out if a particular printer driver uses a user-mode printer driver
when you look into the registry under the following registry setting:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Printers\<printer driver name>\PrinterDriverData

There should be a SPLUserModePrinterDriver entry with the name of the DLL file
containg the user-mode printer driver.
