Using The Init* Signal To Initialize; Computer-To-Printer Communications - Lexmark Printer User Manual

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.
Standard Parallel Connector
The cabling in the following illustration supports Standard and Fastbytes protocols and
IEEE 1284 Nibble, Byte, and ECP protocols.
•
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.
