Thermal Printers

In the previous TWIL, we’ve learned about Thermal printers, their components, communication interfaces & Command language. In this TWIL, we’ll try to communicate with one Label Printer using its command language which is TSPL. Talking to a thermal printer using TSPL #In the previous TWIL, I explored how thermal printers work internally, identified my printer, and successfully established a Bluetooth connection to it using Python.

Topic 1 : Thermal printers #My wife started a small business & got a thermal printer to print the labels for her orders. It’s a new device for me, I’ve never interacted with one, so I decided to investigate how it works & how I can communicate with it & print labels safely, especially since the driver that the seller advised me to use is very suspicious Chinese non-official software.
