Is there a PSA sample in Windows-universal-samples?

Question

Is there a sample for PSA application development in Windows-universal-samples? https://github.com/Microsoft/Windows-universal-samples

I want to develop my PSA application starting with a sample. I read design guide and other documents, but it seems no PSA sample in sample code.

Can anyone help? thanks.

Hello,

I'm not sure if it is helpful to you:

According to the article Print support app design guide - Windows drivers | Microsoft Learn

C# sample code for activation of the Settings UI when launched from any print dialog (MPD/CPD or custom print dialog) or from system settings:

namespace PsaSampleApp

{

sealed partial class App : Application

{

Deferral settingsDeferral;

protected override void OnActivated(IActivatedEventArgs args)

{

if (args.Kind == ActivationKind.PrintSupportSettingsUI)

{

// Get the activation arguments

var settingsEventArgs = args as PrintSupportSettingsActivatedEventArgs;

PrintSupportSettingsUISession settingsSession = settingsEventArgs.Session;

// Take deferral

this.settingsDeferral = settingsEventArgs.GetDeferral();

// Create root frame

var rootFrame = new Frame();

// Choose the page to be shown based upon where the application is being launched from

switch (settingsSession.LaunchKind)

{

case SettingsLaunchKind.UserDefaultPrintTicket:

{

// Show settings page when launched for default printer settings

rootFrame.Navigate(typeof(DefaultSettingsView), settingsSession);

}

break;

case SettingsLaunchKind.JobPrintTicket:

{

// Show settings page when launched from printing app

rootFrame.Navigate(typeof(JobSettingsView), settingsSession);

}

break;

}

Window.Current.Content = rootFrame;

}

}

internal void ExitSettings()

{

settingsDeferral.Complete();

}

}

}

Hi Karlie Weng,

Thank you very much.

According to MS guide documentation, In my sample, OnActivated(IActivatedEventArgs args) is NOT called when I open the print dialog by clicking More Settings in MPD or Preferences in CPD.

And, Package.appxmanifest file is blew.

<Package  xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"  xmlns:mp="http://schemas.microsoft.com/appx/2014/phone/manifest"  xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10"  xmlns:printsupport="http://schemas.microsoft.com/appx/manifest/printsupport/windows10"  IgnorableNamespaces="uap mp printsupport">  

......  

<Extensions>
  <printsupport:Extension Category="windows.printSupportSettingsUI"          
     EntryPoint="MyPSADemo.App"                  
     uap11:SupportsMultipleInstances="true"/>   
</Extensions>

......  

Where am I missing?
