Usage
Axiohm 7193 emulation mode definition, parallel printer
Description
This command sends status data to the host system and is available only on
parallel printers. It is intended for situations when the host computer
requires status but is not capable of IEEE 1284 bidirectional
communications. When this command is sent to the printer, the printer
waits until all the data in the input buffer has been processed. The paper
exhaust line then shows the status for the cash drawer or receipt paper as
follows.
