CONNECTING THE PRINTER
TO YOUR COMPUTER
User's Manual
Your printer has a Centronics parallel interface. An RS-232C serial
interface is a factory-installed add-on option. Installation of the serial
option gives a dual interface where either interface can be connected.
The parallel interface connector has wire clips. The serial interface
connector has tapped holes. Cables for both interfaces are available
from dealers, cable manufacturers, and other suppliers. For detailed
interface specifications, see Appendix D.
Selecting a Parallel Interface Cable
For the parallel interface, use a cable that meets the following specifica-
tions:
At the printer end, use a shielded male Centronics connector,
such as an Amphenol DDK 57FE-30360 or its equivalent. To
prevent RFI (radio frequency interference), the connector cover
must be connected to the cable shield.
At the computer end, most computers (including IBM PCs)
require a male DB-25P connector. Some computers, however,
require a Centronics connector. To determine the type of
connector your computer uses, refer to your computer user
manual.
Make sure that the cable length does not exceed 3 meters
(10 feet).
Selecting a Serial Interface Cable
For the serial interface, use a cable that meets the following specifica-
tions:
At the printer end, use a 25-pin male connector, such as a
Cannon DB-25P or its equivalent.
To determine the type of connector your computer requires,
refer to your computer user manual or ask your dealer.
The cable length can be up to 15 meters (50 feet). This type of
length is required in many networking and shared-printer
configurations.
