Hello Neil,

You must implement this yourself on the native platform using a Dependency Service. Specifically, you would implement the UWP Printing APIs in a DependencyService.

You can find the code to print on UWP here Windows-universal-samples/Samples/Printing at master ยท microsoft/Windows-universal-samples (github.com)

Tutorial and Example

If you are not familiar with using DependencyService in Xamarin.Forms, I strongly recommend that you spend 30 minutes on this tutorial before moving forward. https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/dependency-service/introduction

Once you're done with that tutorial and understand where to put the files (or you are already familiar with DependencyServices) you can review the code in this gist to implement your own service Xamarin.Forms PDF Printing Dependency Service (github.com)

Important - Note that code is a head start, compiled from different open-source sources from forums and StackOverflow and is not intended for production. You should do thorough testing before even considering it ready for your app users.

Feature Request

We do have a Feature Request open for building in Print capability right into the viewer Share PDF for print, email, text, etc (telerik.com)
