During Stewart's talk last night, someone mentioned that Epson receipt printer had too small buffer and had to time print jobs to avoid losing data.

There are 2 ways to get printer BUSY status …

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
