Printing in Adobe AIR (JavaScript / Ajax) whereas skipping the print dialogue

Question

Hi,
Can I do what the topic says? Basically I would like to check with a timer a URL and once something appears there I want it to be sent directly to my default printer.
Is that possible? And if Yes, how?
thank you,
George

Hi, I have not investigated exactly your problem as yet but this seems to be related to it:

For me it was printing only the upper-left corner
but specifing a Rectangle for size for PrintJob.addPage() second argument fixed that
please consult

for help on Rectangle. You can use geom instead of display;
frameworks/libs/air/AIRAliases.js contains an alias directly to geom:
air.Rectangle = window.runtime.flash.geom.Rectangle;
so you may use directly air.Rectangle to construct the size.
It works on AIR 1.5 as well as AIR 2 beta
Code snippet I have used and worked:
function doPrintAir()
    var pjob = new window.runtime.flash.printing.PrintJob;
    if ( pjob.start() )
        var poptions = new window.runtime.flash.printing.PrintJobOptions;
        var rectangle = new air.Rectangle(0, 0, 800, 800);
        poptions.printAsBitmap = true;
        /* poptions.pixelsPerInch = 300; */
        try
            pjob.addPage(window.htmlLoader, rectangle, poptions);
            pjob.send();
        catch (err)
            alert("exception: " + err);
    else
        alert("PrintJob couldn't start");
//comment the line below if you do not want to mess with existing
//window.print
window.print = doPrintAir;
this make js window.print() available for use as one would normay do.
Let me know if this helps and fixes your problem.
