Question

UWP C# Using "Continuation Page" to Print from GitHub.

Hi,

How do I actually use a "Continuation Page" based on a example of GitHub Print code.
What code I should use so Printing a page uses basic printing page + a Continuation Page.

@Voytec-6484 Could you please explain in detail what "Continuation Page" means? There are generally two situations, one is to print multiple pages at a time, such as MainPage and BlankPage1. The other is to print the content of one page to multiple pages. For example, you could print the content of the richeditbox control to multiple pages according to its paragraphs. What about you?

@AryaDing-MSFT I need them both - to be honest - to check which is better.
But I think printing two pages onto two different print pages would be the best.

Thank you for respond!

@Voytec-6484 For your issue, generally, it is always to modify code based on the official sample about printer. You could create a collection and add these pages that need to be printed to this collection. After that, when you add the preview pages, you need to iterate this collection and add them. Therefore, you need to make some changes to the PrintDocument.Paginate event. You could refer to this case to know the detailed code.
