IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS

When the 3270 Datastream Order, Program Tab (0x05) is received by the print service, it is interpreted as a horizontal tab, and three space characters are placed in the print output. However, sometimes the Program Tab will resolve to only two spaces. This problem appears to occur at random.


RESOLUTION

SNA Server 3.0

To resolve this problem, obtain the latest service pack for SNA Server version 3.0. For additional information, please see the following article in the Microsoft Knowledge Base:
Q184307 How to Obtain the Latest SNA Server Version 3.0 Service Pack

To resolve this problem, obtain the hotfix or service pack mentioned in this article. With the updated SNA Print Server fix applied, you can map tabs to a fixed number of spaces based on the size of the first tab in the Set Horizontal Format SCS control code. To do this, perform the steps below after applying the hotfix.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).


NOTE: The registry entry below needs to be created even if a Service Pack is applied. The registry entry is not created by the Service Pack.

  1. Start RegEdt32.exe.


  2. Navigate to the following key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \SnaPrint\Parameters


  3. Add SetFixedTabs = 'TRUE' (the type is REG_SZ).


  4. Stop and Start SNA Print Service for registry change to take effect.
