I'm trying to migrate a WPF application to WinUI 3.
Currently I have the problem that the classes LocalPrintServer and PrintQueue are missing in WinUI 3, whereas PrintDocument is available in the System.Drawing.Printing namespace.
What else can be used to enumerate all printers and select the default printer?
In winui3, you could try to use Print Helper to simplify document printing.
And according to the link that Hans Passant provided: the PrintDocument API hasn't been updated for WinUI3 yet, and it's an accident that the API is showing up right now.
You could also refer to the link:https://github.com/microsoft/microsoft-ui-xaml/issues/7234
Here is a Print Sample in WinUI3
