- sub-function interface

    1 buffer

    buffer size in kbyte. the maximum size is 48 kbyte.

    2 word length

    length of the data to be transferred; values are 7 or 8 bit. the following types are available:

    1 parallel

    2 serial

    3 shared

    in case the shared interface type is selected the printer switchesautomatically between the parallel and serial interfaces. the first data received at the port determine which interface port becomes active. the other interface port will be closed so that only one interface is active at a time (for detailed information see appendix a interface description). - i/f type (interface type)

    word length even parity bit, 9600 baud rate, dtr protocol and auto status = no.

    1 baud rate (only indicated if the serial interface is selected) controls the speed of data transfer. the possible transfer rates are: 600, 1200, 2400, 4800, 9600 or 19200 bps.

    the data transfer will be checked by an even or odd parity bit. the values are: even, odd, none or ignore.

    2 protocol (only indicated if the serial interface is selected) selectable are: dtr, xon/xoff or xon/xoff+dtr.

    the factory setting for the interface type are: shared, 8 kbyte buffer, 8 bit

    3 parity bit (only indicated if the serial interface is selected)

    - auto status (only indicated if the serial interface is selected) possible values: yes or no

    if the auto status is set to yes the host is able to check the status of the printer (for example no paper or printer is in the stop mode).
