DotBot.Aether.Counter

Aether Counter conduit — ESC/POS receipt printer integration for dotbot. Part of the dotbot-aether conduit plugin collection.

What It Does

Translates dotbot event bus events into physical printed records — task tallies, workflow summaries, daily/weekly reckoning receipts. Supports text formatting (alignment, bold, size), two-color printing (black/red), paper cut, font selection, buzzer alerts, and receipt templates. Optimized for Epson TM-U220IIB.
