3270/5250 Print Jobs Generate an Extra Form Feed

• Microsoft SNA Server, version 3.0

SYMPTOMS

Host or AS/400 print jobs that are printed through the SNA Server 3.0 Host Print service, may generate an extra form feed at the end of the print job.

CAUSE

The SNA Server 3.0 Host Print service calls the EndDos API to close to a print session when printing transparent data. The EndDos API always appends a form feed character to the print job even if the Host Print service sent a form feed as part of the transparent data.

RESOLUTION

The Host Print service for SNA Server 3.0 has been updated to use new APIs that do not append a form feed character when closing the print session. The new APIs are StartDocPrinter, WritePrinter, and EndDocPrinter. The EndDos API is no longer used by the Host Print service.

The following modules have been updated:

<Snaroot>\System\Ppd3270.dll
<Snaroot>\System\Winvprt.dll

STATUS

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