PDT-Enabled Print Sessions May Result in Corrupted or Missing Data (315704)

SYMPTOMS

Print sessions that are configured to use a printer definition table (PDT) on Host Integration Server 2000 may cause missing or corrupted print output.

CAUSE

The PDFcomp.exe utility that is included with Host Integration Server 2000 incorrectly truncates all macros that are defined in the printer definition file (PDF) that contain NULL characters (X'00'). This results in a corrupted PDT file, which can cause print output problems, such as missing or corrupted data.

RESOLUTION

To resolve this problem, obtain the latest service pack for Host Integration Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND

This problem does not occur in SNA Server 4.0, so you can usually copy a version of the PDT file from SNA Server 4.0 to the Host Integration Server 2000 server to correct the problem.

A PDT file that is compiled by the PDFcomp.exe utility on SNA Server 4.0 will work on HIS 2000 in most cases. The PDFcomp.exe utility is located in the SNAROOT directory on an SNA Server 4.0 system if the host print service is installed. It is also located in the following folder on the SNA Server 4.0 CD-ROM:

\I386\System\Printsrv

STATUS

Microsoft has confirmed that this is a problem in Microsoft Host Integration Server 2000. This problem was first corrected in Host Integration Server 2000 Service Pack 1.

MORE INFORMATION

The following are some example PDF macros that contain NULL characters:

P10 EQU 1B 7E 02 00 01 32
P12 EQU 1B 7E 02 00 01 3C
P13 EQU 1B 7E 02 00 01 43
P15 EQU 1B 7E 02 00 01 4B
SDW EQU 1B 7E 0E 00 01 09
EDW EQU 1B 7E 0E 00 01 0A

Each of these macros may be truncated at the position where the NULL character occurs.
