Connecting The Printer To Your Computer - Epson LQ-1050 User Manual

Connecting the Printer to Your Computer

Your printer has two separate interface connections: a 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. If you have one of the few
computers that require a different type of interface, you need to
install an optional interface board. See The Interface Boards in
Chapter 5.
The parallel interface is the printer's default setting. If you need to
use the built-in serial interface, be sure to change the DIP switch
setting as shown in Chapter 3.
WARNING: Do not plug more than one interface cable into
the printer at one time. This may damage the printer.
