INT 21 - Novell NetWare - PRINT SERVICES - CANCEL LPT CAPTURE
        AH = DFh
        DL = 02h
Return: AL = status
            00h successful
Desc:   this function ends the capture of the default LPT, removes the job from
          the print queue, and deletes the capture file unless it is a
          permanent capture file
Notes:  this function is supported by NetWare 4.0+, Advanced NetWare 1.0+, and
          Alloy NTNX; under NTNX, it sends a print break (see INT 17/AH=84h)
        after this call, the default LPT defaults to local printing
