KEYWORDS:kbDSupport sna4 kbsna400sp1 kbsna400sp2 kbsna400sp3 kbhis2000 kbhis2000bug kbsna400sp4

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft SNA Server, version 4.0 
 - Microsoft Host Integration Server 2000 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Host Print Service may not process the end of print jobs correctly when the
print sessions are configured to use a print filter dynamic link library (DLL).
The exact symptoms that result from the incorrect end-of-job processing will
vary depending on the print job and on the print filter DLL that is being used.
For example, this problem may result in abnormal termination of the affected
print session or there may be no visible symptoms at all.

CAUSE
=====

The following problems were identified in the Host Print Service when print
sessions were configured to use print filter DLLs:

 - The Host Print Service was passing uninitialized variables to the print
   filter DLL.

 - If a print session was configured to use a Printer Definition Table (PDT)
   file that contains an END_JOB macro, the END_JOB macro was being processed
   after PrtFilterJobEnd() had been called.

 - Under certain circumstances, data passed to the Host Print Service by the
   print filter DLL may have been passed back to the print filter DLL for
   further processing.

==========
