Parallel Interface

Interface Information

The printer communicates with a processor through either a Centronics parallel interface or a pre-installed add-on RS-232C serial interface. The printer cannot use both interfaces at the same time.

This appendix provides information on wiring interface cables or programming for processor-to-printer communications. To simply connect the printer and processor, read the instructions in Chapter 2, “Setting Up the Printer.”

The Centronics parallel interface is the industry standard. It supports the bi-directional data transfer in nibble mode of the IEEE 1284 standard. It is also compatible with the conventional Centronics interface. The cable connector at the printer should be a shielded Amphenol DDK 57FE-30360 or equivalent.

The following table lists the connector pin assignments. Note the following:

•“Input” indicates a signal sent to the printer from the processor.

•“Output” indicates a signal sent from the printer.

•Return lines specified in the “Return pin number” column represent twisted pairs, with one side connected to signal ground.

•The standard signal levels are 0.0 to +0.4 V for low and +2.4 to +5.0 V for high.
