GS z – Request Printer Status
Description
This command returns a single status byte reflecting the printer status, which is
determined by testing the individual bits within the returned status byte. Do not test bits
designated as reserved. All sensor bits defined below are a debounced reading of the
hardware sensors.
For firmware compatibility with previous versions of your printer,
including Series 800 printers, an earlier status bit convention may be
selected at device initialization time via the POR.INI file described in the
chapter Programming for the Epic 950, with status bits interpreted as
documented below.

Compatibility format:
When a compatibility mode for earlier printers is selected at device initialization, the
above byte will instead follow the format used in Series 800 printers prior to firmware
revision 8520. This mode is set using the POR.INI file – this file is documented in the
chapter Programming for the Epic 950. This format is as follows:
Bit Bit = 0 Bit = 1
0 LSB Ticket not low Ticket low
1
This status will also be cleared for a Inner Chassis Open or Head Up. Head Up and Inner
Chassis Open status are available on [GS] S command.
