The epson, epson2 and epkowa backends all support the ESC/I protocol.
The ESC/P protocol that I'm somewhat familiar with is for *printers*
(and printers only, AFAIK).

In your original mail you mentioned ESC S and ESC s commands.  In the
ESC/I protocol those commands are for get-command-parameters and
set-auto-area-segmentation, respectively.  This doesn't jive with what
you described so I doubt those backends will be of any use.

Do your logs include ESC f, ESC G and/or FS F, FS G (status and start
scan commands)?  If not, then these backends definitely aren't what
you're looking for.

Hope this helps,
