7193 Owner’s Guide Commands

Request Alternate Status

This command is available only on Parallel printers. It allows the printer to inform the host when the data in the buffer has been processed, compensating for the lack of bi-directional communication. Status information is limited to what can be sent by the dedicated lines: BUSY, ACK, PAPER EXHAUST, and FAULT.
