问题 I'd like a "print" button on my web-site to print a document with Google Cloud Print, but I want the "url" of the target – a PDF file – to change dynamically, after the button has been clicked (notably, based on what's returned from an AJAX call). The GCP Web Element (GCPWE) seems to have similar functionality, but not quite what I desire. In particular, it seems as though one can only change the "target" (by calling setPrintDocument ) before the button is clicked. Is there a way to specify

问题 My Android app renders a WebView containing a canvas. Cloud Print wants a PDF.

问题 I try to use Google Cloud Print using C#. Internet has just one example, who wrote Josh Goebel. I will not publish the complete example, here is the only method that sends a file to print: public CloudPrintJob PrintDocument(string printerId, string title, byte[] document) { try { string authCode; if (!Authorize(out authCode)) return new CloudPrintJob() { success = false }; HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.google.com/cloudprint/submit?output=json");

问题 Can someone tell me if it is possible to silently print using google cloud print from an android device? The goal is that my app grabs a file from a URL or from the SD card and then sends it to a specific printer - all without interaction from anyone looking at the screen or touching anything. It will actually be triggered by a barcode scan on a blue tooth connected device. Thanks 回答1: Well, it is possible but I don't know why there's not too much information about it in the documentation...
