  --------------------------------------------------------------------------
 
    This function outputs the character whose ASCII value is in DL to the
    standard printer device, which is normally the first parallel port,
    LPT1.
 
       Notes:         If the device is busy, the function waits until it
                      is ready.
 
                      If a Ctrl-Break (Ctrl-C) is detected, INT 23h is
                      executed following output.
 
                      Because this functions offers no way to determine
                      printer status, it is preferable to open the LPT1
                      device as a file.
 
                      For greater control, use the ROM-BIOS services (INT
                      17h).
