I have a scenario where user submit a request and the printer print QR code(QR code have some data).
Note : The printer has connected via third party API node .
Now if the printer runs into problem eg. printer ran out of ink or paper etc.
So while submitting a request if the printer rans into any problem, the user should be notified.
Now I have clue how and where should I start ?
