SNA Print Service Doesn't Support SVF with 5250 Printing (169910)
The information in this article applies to:
- Microsoft SNA Server 3.0
- Microsoft SNA Server 3.0 SP1
This article was previously published under Q169910 SYMPTOMS
The LU 1 SCS Set Vertical Format (SVF) function is not supported for 5250
printing. When the 5250 PPD receives an SVF code, it just ignores it.
STATUS
Microsoft has confirmed this to be a problem in SNA Server 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

MORE INFORMATION
After the fix is applied, when the Print Server receives the following
sequence of bytes in a 5250 data stream, it should recognize and process
the bytes as a "Set Vertical Format" request (the SVF code):
0x2bc2nnvv
The byte nn counts the number of bytes to the end of the SVF code
(including the count byte); the byte vv defines the maximum number of lines
that can be printed on a page (max printable lines [MPL], 0-255).
The fix allows the 5250 PPD to call into the virtual printer DLL to pass
the new MPL value that it receives in an SVF code contained in the data
stream. The virtual printer DLL was also changed to issue a Form Feed (FF)
whenever the row indicated by the MPL is reached.
Note that if the number of lines indicated by the MPL is greater than the
number of lines that will physically fit on the page (given current font
size, LPI, and so on), it is ignored.
