Asynchronous Terminals and Printer Processes Programming Manual

PRINTER PROGRAMMING CONSIDERATIONS

Resetting the 5530

The I/O process performs a RESET when the device is first opened.

A RESET sets all the SETMODE parameters to their SYSGEN values

and causes the 5530 driver to issue <ESC><CR>Q to the printer

to return the operating parameters to their default values. The

physical top of form is preserved. For operations not controlled

by the spooler, the RESET only occurs on the first open if

multiple opens exist on the device.

The spooler issues SETMODE 28 (reset to configured values) at the

beginning of each job. For the 5530 printer, SETMODE 28 resets

SETMODE parameters to their SYSGEN values and reinitializes the

printer in the same manner as when the device is first opened.

SETMODE 29 (set auto answer or control answer) is the only

SETMODE parameter that is not affected by SETMODE 28 or RESET on

OPEN.

Do not press the RESET button on the printer during printing.

Doing so can cause data to be lost. Pressing the RESET button

does not reset programmable parameters or top of form.

Pressing the RESTORE button on the printer does reset pro-

grammable parameters and top of form.
