Standard Parallel Connector

The standard IEEE 1284-B compliant parallel connector on the printer is a 36-pin
D-shell female receptacle, as shown.

Using the INIT* Signal to Initialize

When the printer is using the parallel interface and it receives an INIT* signal, it
initializes as follows (unless INIT* is disabled by a variable default setting):

Computer-to-Printer Communications

This section describes how the parallel interface receives data from the computer.

•
It prints data received before INIT*, and then initializes.
•
It returns variable defaults to the values stored in the user default settings.
•
It returns fixed default settings to the factory values.
•
It retains permanent downloaded fonts and macros, but deletes temporary
downloaded fonts and macros.
•
The link buffer remains intact.
•
Variable default paper size settings become the active paper formatting size.
•
If paper is loaded in a tray with auto size sensing, the printer resets the active
default paper formatting size to the size of the paper in the tray.
•
INIT* is not honored when Hex Print is active.
•
INIT* causes the parallel interface to go busy. The printer processes INIT*
when the parallel interface becomes active and all preceding characters have
been processed.
