Connecting The Printer To Your Computer - Epson LQ-850 User Manual

Connecting the Printer to Your Computer

Your LQ printer has two separate interface connections: a
®
Centronics compatible parallel interface and an RS-232C
compatible serial interface. If you are not sure which one is
required by your computer, check your computer manual for this
information. If you have a suitable shielded cable, you should be
able to connect to most computers immediately.
The printer is set up for parallel data communication at the
factory. If you need to use a serial interface, be sure to adjust the
DIP (Dual In-line Package) switch settings as shown in the section
on DIP switches in Chapter 3.
The few computers requiring other types of interfaces can
probably use one of the optional interfaces described in the section
on interfaces in Chapter 7.
Do not plug more than one interface cable into the printer
at one time. This may damage the printer.
