Detecting a printer connection

 

I was trying to find the printer state, though QPrinter provides QPrinter::printerState
Returns the current state of the printer. This may not always be accurate (for example if the printer doesn’t have the capability of reporting its state to the operating system).

is there any way to monitor the printer when it is connected and disconnected and receive events in the application?

printerState returns the state of the printer, as you said.

QPrinter::Idle 0
QPrinter::Active 1
QPrinter::Aborted 2
QPrinter::Error 3

You can just set up a signal that checks if the printer is active or not based on the above chart, which could then trigger your events.
