The information in this article applies to:

  • Microsoft Host Integration Server 2000
This article was previously published under Q326084
IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry

SYMPTOMS

Host print jobs that contain Printer Control Language (PCL) codes are not formatted correctly because PCL codes similar to the following are printed instead of being processed by the printer: 
&l0O (8U (s0p10.00h12.0v0s1b3T &k0G

CAUSE

This problem occurs because the embedded PCL codes under 0x40 that are present in LU1 print jobs are converted to spaces. For example, EBCDIC 0x27 (an Escape character) is converted to ASCII 0x20.

WORKAROUND

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
  1. Start Registry Editor (Regedt32.exe).
  2. Locate the following key in the registry, and then click to select this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SnaPrint\Parameters
  3. On the Edit menu, click Add Value, and then add the following registry value:

    Value name: HonorCharsUnder0x40
    
   Data type:  REG_SZ
    
   Value data: TRUE

  4. Quit Registry Editor.
NOTE: You must stop the SNAPRINT service, and then restart the service for the parameter to take effect.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION

NOTE: By default, Host Integration Server 2000 should honor PCL characters under 0x40. Earlier versions of SNA Server, by default, ignored characters under 0x40 and required the registry parameter mentioned in the "Workaround" section.

When this problem occurs, SNA Print Internal traces (SPRTINTx.ATF) show the following statements:
