Interfaces
Your printer offers by default the possibility of operating either via USB or
Ethernet. Optional, an parallel or serial interface can be used.
This chapter informs you about the USB and Ethernet interface and the optional
serial and parallel interface and describes the communocation between your
computer and the printer.
The USB, the internal ethernet and the optional parallel and 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 interfaces
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 sequence
described restarts. If incoming data is on the other interface and the current print
position is not “Top of Form”, a form feed is carried out.
If shared = parallel or shared = serial is set, all other interfaces are disabled.
In the chapter Options, the interfaces which can be purchased with your printer
are listed.
