SYMPTOMS
When a zero-length RU is sent to the SNA print server as part of a host print job, a blank page will be printed. The following is an example of a zero-length RU as captured in a SNA Server Data Link Control Message trace:
04160080->01020101 DLC DATA
DAF:EC OAF:01 ODAI:off Normal
RQE FMD BC EC DR1 PI BB EB
---- Header at address 01034418, 1 elements ----
04B00004 00002C00 EC010004 01002102 <......,.......!.>
---- Element at address 0152D5A4, start 10, end 12 ----
0391C0 <.j. >
The Element portion of the preceding frame contains a Request Header (RH) of x'0391C0', but no actual data.
CAUSE
Print Server treats the zero-length RU as a unique print job where 0D 0C (CR FF) is sent to the printer. The print server calls "StartDoc" to start a new document as soon as it receives a request, and "EndDoc" when the document is complete. Even though there is no data submitted to the printer between the "StartDoc" and "EndDoc" calls, the printer will still print a form feed (FF).
RESOLUTION
There are two possible workarounds for this issue:
- Configure the print session to use a PDF file. The PDF file uses "StartDocPrinter" and "EndDocPrinter" which do not automatically produce a FF. For instructions on configuring PDF files, refer to the SNA Server online help Chapter 6 Printer Definition Files.
-OR- - Use the DelayPrintStart Registry parameter as discussed in the following Microsoft Knowledge Base article:
