SNA Server Print Server Always Inserts CR/LF

• Microsoft SNA Server, versions 3.0, 3.0 SP1

SYMPTOMS

When printing, SNA Server Print Server will insert its own carriage return/line feed (CR/LF) at the column that is indicated in the Default Page Width value in the Printer Properties. However, some print jobs control their CR/LF with 3270 Orders using Set Buffer Address (SBA), in an SCS Code ('15' EBCDIC or '0A' ASCII), and/or in Escape Sequences (either in transparent sections or not).

NOTE: The Escape sequence that tells the printer to do the wrapping is:

<Esc>&s0C <-End-of-line wrap = 0

0 = enable End of line Wrap
1 = Disable End of Line Wrap

RESOLUTION

A fix is available to correct this problem. To prevent SNA Print Server from inserting its own CR/LF, apply the fix referenced below and then edit the registry as follows:

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

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: LineWrap
   Data Type: REG_SZ




4. Click OK.



5. In the String field, input the string TRUE and then click OK.



6. Stop SNAPrint Service and SNA Server Manager.



7. Copy the fixed DLLs to the <Snaroot>\System directory.



8. Restart SNAPrint Service and SNA Server Manager.
