App page not printing using button

Question

Hi I have tried to print an app screen using button but it is throwing an exception like 

WinRT information: Windows.Graphics.Printing.PrintManager is not supported on the view provided.

This is my code..

XAML

<Button x:Name="invokePrintingButton" Content="Print" Margin="0,0,10,0" Click="InvokePrintButtonClick"/>

C#

  private async void InvokePrintButtonClick(object sender, RoutedEventArgs e)
        {
            if (this.ActualWidth >= 768)
            {
                await Windows.Graphics.Printing.PrintManager.ShowPrintUIAsync();
            }
        }

I am not getting why it is throwing exception..

Can any one please help me on this ?

Thank you in advance..

Answer 1

Have you registered the page with the PrintManager? The page needs to support printing before it can bring up thru printing UI. See Quickstart: Printing from your app

Answer 2

No but I have actually tried this step

How to print using an in-app print button (Windows Store apps using C#/VB/C++ and XAML)

Answer 3

You need to register the page. The Quickstart starts with a sample that already supports printing.

Answer 5

If only printing was that simple.

You need to get into the sample printing example.

Its quite involved.

I found I had to do it in two steps.

1/ Set up printer job from parameters like area to print etc.

2/ Actual print which is linked into sample printer code.

It should keep you out of mischief for a while working out which bits of code to use etc.

Answer 6

Note that Nigel is writing a DirectX app and so doesn't have access to the Xaml helpers which handle printing and pagination. The basic concept is the same, but the way the app handles the document itself is quite different in DX and in Xaml.
