8-12 Interfaces 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): • 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. Computer-to-Printer Communications This section describes how the parallel interface receives data from the computer.
