 Name:         »Character printer output status« - Check the status of 
               the printer port.

 Opcode:       17

 Syntax:       int16_t Cprnos ( void );

 Description:  The GEMDOS routine Cprnos checks whether handle 3 - 
               normally the parallel port prn: - is ready to accept 
               characters.

               Note: It is strongly recommended to use this function 
               before starting a printout, since it takes around 30 
               seconds to recognize a printer timeout if the printer 
               is not ready (perhaps not switched on?).

 Return value: The function can return the following results:

                Value  Meaning

                0      Printer is not ready
