Google JavaScript API - Chrome.printerProvider: Printer id format

问题

I trying to use chrome.printerProvider to make a printing extension. Can anyone give me an example about PrintInfo id ? I'm request print via network and I setting PrintInfo Id by printer address but it's not working. Here is my script:

chrome.printerProvider.onGetPrintersRequested.addListener(function callback(resultCallback) {
    resultCallback([{
      id: '192.16.1.18', // printer address
      name: 'My Printer',
    }]);
});

or

chrome.printerProvider.onGetPrintersRequested.addListener(function callback(resultCallback) {
    resultCallback([{
      id: 'net://192.16.1.18', // printer address
      name: 'My Printer',
    }]);
});

This should work..

chrome.printerProvider.onGetPrintersRequested.addListener(
    function ( resultCallback ) {
        resultCallback( [{
      id: 'net://192.16.1.18', // printer address
      name: 'My Printer',
    }] );
    }
);
