Log list of available printers and their URLs

Question

I am attempting to set up a UIPrinter instance so that my iPad app can print directly to that printer without having to present the print controller dialogue. The problem I'm having is that I can't seem to find the URL of this printer. It is connected via AirPrint.

Visiting http://localhost:631/printers/ does show the printer, but it shows the USB version of the printer's URL (i.e. usb://Brother/QL-710W?serial=12345).

What I am wondering is, how can I print (to the debug output) a list of my available printers, and their URLs? I figure by doing this I can then locate my printer's AirPrint URL and go from there.

Thanks!

Here's a simplified version in Swift 3 for anyone stumbling upon this same question in 2017:

let pickerController = UIPrinterPickerController(initiallySelectedPrinter: nil)

pickerController.present(animated: true) { (controller, completed, error) in
    if completed == true {
        print(controller.selectedPrinter!.url)
    }
}
