Connecting the Printer to Your Computer

For the laser printer to be able to receive and interpret information

from your computer, both devices need to be set up so that they can

communicate correctly. This requires having

the correct

interface

cable and selecting

the

right communications settings. You

can

select from

the

following built-in interfaces:

l

Parallel

l

RS-232C serial

l

RS-422A serial.

Choosing an interface

When connecting the laser printer to your computer, you first have

to determine whether a parallel or serial connection should be used.

Many computers only provide one type of connection for a printer.

If both serial and parallel connections are available, it is normally

better to use

the

parallel interface for the printer, leaving the serial

port of your computer free for devices such as modems. If you are ii

any doubt about which type of connection to make,

consult

your

computer dealer.
Your printer is set up at the factory for parallel communication. If

your computer also uses parallel communication, you should be

able to connect up immediately, provided you have a shielded

parallel interface cable.

If, however, you find

that

you need a serial interface, you must

change the communications settings with SelecType as described in

Chapter 3. You also need to find out which type of serial interface is

required by your computer (RS-232C or RS-422A) and set the

printer’s DIP switches accordingly. (The DIP switches are factory set

for the RS-232C serial interface.)
