In UWP app if you want to use a Windows Driver Printer than I am sorry the only option is to print using the Print Popup dialog.
If you want to print to a specific printer without print dialog then there are two ways-
- The printer should be OPOS based and you can use PosPrinter class to print to a specified printer(This uses OPOS drivers)
- If you want to use Windows driver printer then you need to use Windows brokered component and then use the classic .NET code to provide a wrapper to print to a specific printer, but you need to have your app through sideloading.
I hope this solves your problem.
