Int 61 Fn 0005  - Banyan Vines - Print Service Control                     [N]

   AX = 0005h
   DS:DX -> request block (see #3099)

Return: AX = status
       0000h successful
       0001h network software not installed or incompatible

Notes: This service is handled by the redirector
   The size of the request/result block depends on the selected function
     and the value at offset 04h.

Format of VINES request/result block for printer control:
Offset Size    Description (Table 3099)
 00h   WORD    function
       0201h "endspool" all data for a print job has been sent
             (no bytes returned)
       0202h "deassign" the virtual printer port
           Before the printer port is deassigned all data sent
             to it is endspooled.
             (no bytes returned)
       0205h "get_active" get currently active printer port
             (1 byte required for result)
           Returns:  - the currently active printer port (1-3) (0 if
                 there is none)
       0207h ??? purpose unknown; called periodically every second
       020Ch "get_bannertitle" gets the title which is printed on the
             banner page of a print job sent to the virtual port
             (16 bytes required for result)
           Returns:  - the null-terminated banner title
       020Eh "get_servicename" gets the name of the print service
             assigned to the virtual port
             (64 bytes required for result)
           Returns:  - the null-terminated print service name assigned
                 to the virtual port
       0210h "set_bannertitle" sets the title which is printed on the
             banner page of a print job sent to the virtual port
             (16 bytes required for input)
           Input:  - the null-terminated banner title (max 16 chars)
       0212h "set_servicename" sets the name of the print service
             assigned to the virtual port
             (64 bytes required for input)
           Input:  - the null-terminated print service name
                 (max 64 chars)
       0216h "get_job_paper_format" gets the paper format for
             subsequent print jobs
             (16 bytes required for result)
           Returns:  - the null-terminated paper format
       0217h "set_job_paper_format" sets the paper format for
             subsequent print jobs
             (16 bytes required for input)
           Input:  - the null-terminated paper format (max 16 chars)
 02h   WORD    number of active virtual port (1-3) (0 for function 0205h)
 04h   WORD    Offset into the request block from which additional input
         is to be read and/or at which the result is to be copied
         (if there is any). Therefore the smallest block size for a
         function which returns a result is
           this offset + the maximum number of returned bytes - 1
 06h   WORD    0000h
