CONNECTING THE PRINTER
TO YOUR COMPUTER
User's Manual
Your printer supports one of the following interface options:
• Centronics parallel interface only
• Centronics parallel interface+RS-232C serial interface
• Centronics parallel interface+USB (+LAN) interface
The RS-232 serial interface is a factory-installed option for a Centronics
parallel interface model. Installation of the serial option provides a dual
interface feature enabling the connection of either interface but inhibiting the
operation of both interfaces at the same time.
The parallel interface connector has wire clips. The serial interface connector
has tapped holes. Cables for these interfaces are available from dealers, cable
manufacturers, and other suppliers.
The LAN card is a user installable option. For details, see Chapter 8 or refer to
the Online Manual that comes with the LAN card.
For detailed interface specifications, see Appendix D.
Selecting a Parallel Interface Cable
For the parallel interface, use a cable that meets the following specifications:
√ 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 specifications:
√ 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.
