SYMPTOMS
If a host print job sends a line of print data with a Carriage Return (CR) and Line Feed (LF), print server may swap these control characters such that the printer receives the LF followed by the CR.

Under normal circumstances, this does not cause any problems with the actual print output. However, if the print job is sent to an application (instead of a printer) that parses the data, problems could occur if the application expects to receive the CR and LF in a specific order.



CAUSE
The SNA Server print service swaps the order of a CR and LF if the print data caused the specified Maximum Print Position (MPP) to be reached before the CR and LF commands are received.



RESOLUTION
To resolve this problem, obtain the latest service pack for SNA Server 4.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Microsoft SNA Server versions 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3.

This problem was first corrected in SNA Server 4.0 Service Pack 4.
