This article was previously published under Q181026

SYMPTOMS

The SNA Server Trace program (Snatrace.exe) cannot do byte- for-byte tracing of print jobs when tracing the SnaPrint service. The Internal Trace tab of the SnaPrint Properties page allows has options to enable all of the internal functions of the Host Print Service, but it does not include an easy method to see how the print data is being processed.

CAUSE

The SNA Server Trace program included with SNA Server 3.0, 3.0 SP1, and 3.0 SP2 was not designed to support this level of print data tracing in SNA Server 3.0.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 SP1, and 3.0 SP2.

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 (without the spaces):

MORE INFORMATION

With this update applied, the Internal Trace tab for all of the listed SNA Server services includes a new checkbox for "Custom Conditions". The SnaPrint service is the only services that currently implements new tracing when the "Custom Conditions" option is selected.

If "Custom Conditions" tracing is enabled for the Host Print service (SnaPrint), the resulting print service internal tracing will capture a byte-for-byte breakout of the data contained in the print job(s) sent to the print service. The new tracing option applies to LU1, LU3, and APPC printing. The following is an excerpt from a LU1 print job when "Custom Conditions" tracing is enabled:
