SNA Server Issues with DBCS Printing to an AS/400 (164794)

SYMPTOMS

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
   					

2. 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.
3. 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.
4. 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.
5. 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.)
6. 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.
7. 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.
8. 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=??
