DOCUMENT:Q180941 07-SEP-2001 [sna] TITLE :APPC Printing Misinterprets ASCII Data PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:3.0,3.0 SP1,3.0 SP2,4.0 OPER/SYS: KEYWORDS:kbprint ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== During printing, the parser prematurely terminates the ASCII Transparent section, and begins to interpret the data as SCS codes. When this occurs, the SNA Print service may log the following event in the Windows NT Application Event Log: Event ID: 4101 Source: PPV5250 Description: SCS parser has detected a parameter error. CAUSE ===== The Closeprinter routine is not setting a pointer to NULL, which may cause calls to open a print session to fail at a later time. This results in Print Server losing track of its position in the datastream, causing some of the data to be misinterpreted as SCS codes instead of transparent data. STATUS ====== Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 SP1, 3.0 SP2, and 4.0. This problem was corrected in the latest SNA Server versions 3.0 and 4.0 U.S. Service Packs.
