iOS printing to a printer on the network

[Shikamu]

Hello,

I'm trying to make an iOS application that can "automatically" print pictures to a printer that's on the network. I'm fairly new to iOS and Qt but so far I've not been able to find out how to do the printing. I found some examples that show me how I can use bonjour (https://doc.qt.io/archives/qq/qq23-bonjour.html), I think I can more or less find my printer like this but I couldn't find any help so far on how to use QPrinter to automatically connect to that printer.
Basically my code so far is essentially:

QPrinter printer;
printer.setOutputFormat(QPrinter::NativeFormat);
printer.setPrinterName("Canon SELPHY CP1200");
QPainter painter;
if(!painter.begin(&printer))
{
  //failed, we actually hit this at the moment
  return 1;
}
painter.drawText(10, 10, "Test !");
painter.end();

I think the problem is that I need to somehow connect the device to my Canon printer somehow but I don't know how to do that. Any insight would be greatly appreciated :)

Cheers!
