another EPSON serial printer language that is bi-directional. That language is called Remote Mode. It is entered from ESC/P

or ESC/P2 mode.

Remote Mode commands should not be sent to the printer in between consecutive ESC/P2 commands.

The primary purposes for EPSON Remote Mode printer control language are to provide the host with the following:

1) Current printer status

2) Printer identification

3) Capability of setting the printers front panel operations remotely (print the nozzle check pattern, clean print

heads, set hard ware adjustments for paper size and thickness, save current settings into NVR (non-volatile RAM,

print the dot alignment test pattern, etc.)

The Remote Mode command architecture is as follows:

Enter Remote Mode (leave ESC/P or ESC/P 2)

- change printer settings (model dependent) via Remote Mode Set commands and/or

- request printer settings (model dependent) via Remote Mode Reply commands

Exit Remote Mode (enter ESC/P or ESC/P 2)
