This is a service to connect ESC/POS compatible receipt printers to a MQTT broker. Use this in your smart home or for printing receipts!
Further documentation can be found here.
There also is a HomeAssistant Add-On at https://github.com/jhbruhn/escpos2mqtt-hassio.
This server allows you to print receipts using programs sent via MQTT. Programs look like this:

justify left
writeln "Item 1 $10.00"
writeln "Item 2 $15.00"
underline single
writeln "Total: $25.00"
underline none
feed 2
justify center
qr_code "https://example.com/receipt/12345"
feed 2
cut
