Thanks for that, but many of the cheap non-Epson clones use a weird
subset of ESC-POS. The Xiamen DP Electronics DP-EH600 command set -
which seems to be the standard most people stick to, most likely because
it has a manual in English - only supports 'GS a' ASB codes.

It's an interesting situations where lots of companies produce
essentially the same printer by using the same no-brand (but quite nice:
ARM Cortex-M0 based) controller.

cheers,
 Stewart
