This repo is VERY MUCH work in progress. Unimplemented functions WILL panic. This lib is prone to change.
I'm intending on working on a wack printer project and quickly discovered ESC/POS is somewhat of a mess. Most implementations of the "protocol" are vendor specific despite offering similarities. This repo aims at implementing the Rongta RP325/RP326/RP327/RP328 command set.
The command set is implemented based off this manual which is everything but great. My guess is it's been translated from some language (chinese maybe?) to english using the shittiest and first translator software someone at Rongta could find.
Kanjis are currently unsupported by this library
