No matter which printer I select, I get "Print-job failed: Unsupported document format "application/pdf".
我只想在惠普印刷厂印刷。
I see no place in code to change the output type.
I am using UISimpleTextFormatter to format the string.
Not sure how to get around this one.
http://www.ohchr.org。 下面的《法典》从Miguel s例子中简单明了。 唯一区别是,我尝试了标本,看看它是否以不同于application/pdf的格式获得产出。
The print dialog comes up with the list of HP printers, I select a printer but nothing gets printed and in debug mode, the error specified at the top gets logged.
除UIPrintInfoOutputType. General外,我还尝试了UIPrintInfoOutputType.GrayScale,但效果相同。
public partial class AppDelegate : UIApplicationDelegate

window.MakeKeyAndVisible ();
var button = UIButton.FromType (UIButtonType.RoundedRect);
button.Frame = new RectangleF (100, 100, 120, 60);
button.SetTitle ("Print", UIControlState.Normal);
button.TouchDown += delegate {
Print ();
};
window.AddSubview (button);
return true;
}
void Print ()
{
var printInfo = UIPrintInfo.PrintInfo;
printInfo.JobName = "Test :";
printInfo.OutputType = UIPrintInfoOutputType.General;
printInfo.JobName = "Test: My first Print Job";
