Hello hackers, I've created a medium post on how to print receipts with thermal printers using ESCPOS commands.

In the Settings screen, under the Payments section click on Receipt & Invoice Printing General Settings. In the Thermal Printer (https://ca.munbyn.com/collections/all-printers) section select 80mm Receipt as the Receipt format and select your printer as the Receipt printer type. Tick the Print receipt ticked by default field to always print receipts when making a payment.
