C# Класс PrintSample.DisablePreviewPrintHelper

This class customizes the standard PrintHelper in order to disable print preview.
The PrintTaskRequestedMethod sets printTask.IsPreviewEnabled to false in order to disable print preview. Since print preview is disabled, the Paginate event will not be raised. Instead, the pages to be printed are generated in response to the AddPages event.

AddOnePrintPage ( RichTextBlockOverflow lastRTBOAdded, PrintPageDescription printPageDescription ) : RichTextBlockOverflow

AddPrintPages ( object sender, AddPagesEventArgs e ) : void

This is the event handler for PrintDocument.AddPages. It provides all pages to be printed, in the form of UIElements, to an instance of PrintDocument. PrintDocument subsequently converts the UIElements into a pages that the Windows print system can deal with.
PrintTaskRequested ( PrintManager sender, PrintTaskRequestedEventArgs e ) : void

This is the event handler for PrintManager.PrintTaskRequested. In order to ensure a good user experience, the system requires that the app handle the PrintTaskRequested event within the time specified by PrintTaskRequestedEventArgs.Request.Deadline. Therefore, we use this handler to only create the print task. The print settings customization can be done when the print document source is requested.
