256986 Description of the Microsoft Windows Registry


SYMPTOMS

AS/400 applications that require specific page width (or maximum print position) settings may not print correctly when printed via a 5250 print session configured in SNA Server 3.0 or 3.0 SP1. Print jobs that have truncated lines are one example of how this problem may appear.

CAUSE

The SNA Server print service only supports a limited range of values for the Maximum Print Position (MPP) SCS control code for the 5250 data stream. The supported values for 5250 printing are 80, 132, 158, and 198.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION

With the fix applied, the SNA Server print service accepts MPP SCS control codes in the 5250 data stream for any language and to change the line length accordingly. The print service will also set an overall MPP value for each print job as it starts. To set this value, edit registry as follows.

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.


NOTE: This registry parameter is only needed if you want a default MPP value for each print job. If each print job includes an MPP SCS control code that sets the line length, this registry entry is not required.

  1. Start Registry Editor (Regedt32.exe or Regedit.exe, as appropriate for your version of Windows NT).
  2. Go to the following key in the registry:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\snaprint\ 
    parameters
                            
  3. On the Edit menu, click Add Value and use the following entry:

    Value Name: mpp
    Data Type: REG_SZ

    In the Value field, type a value between 40 and 255. The Default value is 132. The range is 40-255.
  4. Exit Registry Editor.

This registry parameter is only needed if you want a default MPP value for each print job. If each print job includes an MPP SCS control code that sets the line length, this registry entry is not required.
