 Last reviewed: April 14, 1997
Article ID: Q164794
The information in this article applies to:
  • Microsoft SNA Server, version 3.0

This article only applies to DBCS (double byte character set) code pages. DBCS code pages include all of the following: 

   290 Japanese (Katakana)
   930 Japanese (Extend Katakana)
   931 Japanese (English-lower)
   933 Korean
   935 Chinese (PRC)
   937 Chinese (Taiwan)
   939 Japanese (Extend English)

  • Carriage Return (0x0D) Not Interpreted Correctly with 5250 Printing

  • Print Server Doesn't Send Form Feed (FF) When NL or LF Is on Last Line

  • Last Line Doesn't Print When Using SNA Server Print Server

  • SNA Server Print Server Ignores the First LF and NL

  • Problem with PrintPosition (AbsoluteHorizontalMove)

  • Added Support for Thick Dotted Line, SHF, SPCC, and STO

  • FF Command Is Not Positioned at Line-1 Column-1 of Next Page

  • Application Exception in Snaprint.exe with STO

    1. Carriage Return (0x0D) Not Interpreted Correctly with 5250 Printing

    SYMPTOMS

    Sending the following sequence to the 5250 Print Service (J version) 

       "AAAA"+CR+LF+"BBBB"+NL (interpreted to ASCII for clarity)
    Will result in: 

       AAAA
       BBBB
    The expected result is: 

       AAAA
   BBBB

    1. Print Server Doesn't Send Form Feed (FF) When NL or LF Is on Last Line

    SYMPTOMS

    When using the SNA Server Print Server (J version) to print to an AS/400, and a new line (NL) or line feed (LF) character is on the last line of the printable area, a form feed (FF) is not generated. Therefore, any remaining printable text is not printed on the next page.

    1. Last Line Doesn't Print When Using SNA Server Print Server

    SYMPTOMS

    When using the SNA Server Print Server (J version) to print to an AS/400, the last line may not print. The SNA Server Print Server (J version) does not correctly flush the write buffer for an end-of-page.

    1. SNA Server Print Server Ignores the First LF and NL

    SYMPTOMS

    SNA Server Print Server ignores the first line feed or new line it comes across.

    1. Problem with PrintPosition (AbsoluteHorizontalMove)

    SYMPTOMS

    The following is a sample datastream (converted to ASCII for ease of readability): 

       "AAAAA"+LF+PP(AHM 3)+"BBBB"+NL
    The expected result is: 

       AAAAA
      BBBBB
    The actual result is: 

       AAAAA

   ("BBBB" was not printed.)

    1. Added Support for Thick Dotted Line, SHF, SPCC, and STO

    SUMMARY

    The following features have been added to DBCS printing in the SNA Server 3.0 J version:

    • Support for Thick Dotted Line.
    • Support for the Set Horizontal Format (SHF) SCS command to support Max Print Position (MPP).
    • Support for the Set Presentation of Control Character (SPCC) command, to support the presentation of control characters (SI/SO).
    • Support for the Set Text Orientation (STO) command, to rotate a DBCS character.

    These changes were made to the DBCS environment, and do not include SBCS.

    1. FF Command Is Not Positioned at Line-1 Column-1 of Next Page

    SYMPTOMS

    The following is a sample datastream:

    Sent data: 

       "12345" (NL) "67890" (FF) "ABCDE"
   (NL:New Line)
    The following is the result: 

       <Page 1>
   12345 <line 1>
   67890 <line 2>

   <Page 2>
     <line 1>
       ABCDE   <line 2>
    Notice the ABCDE is indented to the right; it should be left justified.

    1. Application Exception in Snaprint.exe with STO

    SYMPTOMS

    When printing to an AS/400 using SNA Server 3.0 Print Server and selecting a DBCS character set, a general protection fault (GPF) occurs if you send a print job with STO in its datastream.

    The GPF is in the following function: 

       WinVPRTSetTextOrientation within SNAPrint.exe.
    The following is the assembler call: 

       cmp     byte ptr [edx],0x40          ds:00000000=??
