Interfaces
Your matrix printer offers the possibility of operating either via a parallel
or via a serial interface. This chapter informs you about the parallel Cen-
tronics compatible interface and the serial interface type RS232C/V.24
and describes the communication between your computer and the
printer.
These interfaces are linked to form a so-called shared interface. Your
printer can be configured to use only one interface or both alternately.
When only one interface is used, it is monitored by the printer. If the
printer is configured to use both interfaces simultaneously it monitors
both interfaces for incoming data. As soon as the printer recognizes a
signal it switches to the respective interface and sends the BUSY signal
to the other interface. After finishing the data transmission, the printer re-
mains switched to the interface for a certain period of time (30 seconds).
When this time has elapsed, the controller reenables both interfaces and
the sequence described restarts. If incoming data is on the other inter-
face and the current print position is not “Top of Form”, a form feed is
carried out.

chased with your printer are listed.
