Interfaces
Your printer offers by default the possibility of operating either via a
parallel, an Ethernet or via an optional serial interface.
This chapter informs you about the parallel Centronics compatible
interface, the Ethernet interface and the optional serial interface and
describes the communication between your computer and the print-
er.
The parallel and the optional serial interface are linked to form a so-
called
shared interface
. Your printer can be configured to use only
one interface or all alternately. When only one interface is used, it is
monitored by the printer. If the printer is configured to use all inter-
faces simultaneously it monitors all 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 interfaces. After
finishing the data transmission, the printer remains switched to this
interface for a certain period of time (30 seconds). When this time
has elapsed, the controller reenables both interfaces and the se-
quence described restarts. If incoming data is on the other interface
and the current print position is not “Top of Form”, a form feed is car-
ried out.
In the chapter

, the interfaces which can be pur-
chased with your printer are listed.
