Setting up the printer

2-11

Your printer supports one of the following interface options:

Centronics parallel interface only
Centronics parallel interface and RS-232C serial interface
Centronics parallel interface and USB interface

The RS-232 serial interface is a factory-installed option for a Centronics parallel in-
terface model.  Installation of the serial option provides a dual interface feature en-
abling 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 manufac-
turers, and other suppliers.  
The LAN adapter is a user installable option. For details, refer to the Manual that 
comes with the LAN card.

For detailed interface specifications, see Appendix D.

For the parallel interface, use a cable that meets the following specifications:

3

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 deter-
mine the type of connector your computer uses, refer to your computer user manual.

3

Make sure that the cable length does not exceed 3 meters (10 feet).

For the serial interface, use a cable that meets the following specifications:

3

At the printer end, use a 25-pin male connector, such as a Cannon DB-25P or its 
equivalent.

3

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.
