使用 System.Print 在“Microsoft Print to PDF”打印机中设置文件名

Question

I want to save an IDocumentPaginatorSource , eg FixedDocument or XpsDocument , as a PDF by using the virtual printer "Microsoft Print to PDF":

var printServer = new System.Printing.PrintServer();
var queue = printServer.GetPrintQueue("Microsoft Print to PDF");
var writer = System.Printing.PrintQueue.CreateXpsDocumentWriter(queue);
writer.Write(Document.DocumentPaginator); // Document = IDocumentPaginatorSource

This works, but makes the printer open a file save dialog. I would like to set the file name programmatically and either suppress this dialog completely or at least set the initial file name in the dialog. Is this possible?

I know, that this can be done when using System.Drawing.Printing.PrintDocument by setting PrinterSettings.PrintFileName and PrinterSettings.PrintToFile (see 1 , 2 ), but this is the old printing framework that does not support IDocumentPaginatorSource .

I checked all classes in the System.Printing namespace but did not find any way to set these two settings. Maybe it's possible to retrofit these seetings into the PrintTicket by extending the print schema ? If so, how exactly would you do that?

I don't have a solution using the "Microsoft Print to PDF printer", but if you switched to using the Win2PDF printer driver you can set the file name programatically through the registry. To do this, see the documentation for the "PDFFileName" or "PDFDefaultFileName" registry settings.
