There will be a pool of thermal transfer printers (model not yet determined). It is necessary to listen to the events 'some button is pressed' on printers in order to instruct the information system to print a barcode on this event. Tell me in which direction to dig - how to listen to this event?

Why not dig aside "What the hell is with the buy button, so that pressing the button is tracked over the network and transmitted to the information system to print a barcode"

The printer is an output device, not an input.
