Int 2Fh / 0104h         Hold Print Jobs and Get Status               DOS 3.0+

    Stops the current print job and returns the address of the PRINT
    queue.

        Entry   AX = 0104h

        Return  DX    = Error count
                DS:SI = Pointer to print queue

    ──────────────────────────────────────────────────────────────────

    The print queue consists of a series of 64-byte entries, each
    containing a zero-terminated string specifying the path of a file
    in the queue. The first file in the list is the one currently
    being printed. The last entry in the list consists of a single
    null character.

    Programs must not change the contents of the print queue. To add or
    remove a file from the queue, use Int 2Fh functions 0101h or 0102h.

    The print spooler continues to hold the current print job until
    Int 2Fh function 0105h (Release Print Jobs) is called.
