Programmatically set filename and path in Microsoft Print to PDF printer

Question

I have a C# .net program that creates various documents. These documents should be stored in different locations and with different, clearly defined names.

Answer 1

I did some experimenting myself but like yourself was also not able to prefill the SaveAs dialog in the PrintDialog with the DocumentName or PrinterSettings.PrintFileName already filled in the PrintDocument instance. This seems counterintuitive, so maybe I'm missing something

If you want to, you can however bypass the printdialog and print automatically without any user interaction at all. If you choose to do so, you must make sure beforehand that the directory to which you want to add a document to is in existence and that the document to be added is not in existence.

string existingPathName = @"C:\Users\UserName\Documents";
string notExistingFileName = @"C:\Users\UserName\Documents\TestPrinting1.pdf";

if (Directory.Exists(existingPathName) && !File.Exists(notExistingFileName))
{
    PrintDocument pdoc = new PrintDocument();
    pdoc.PrinterSettings.PrinterName = "Microsoft Print to PDF";
    pdoc.PrinterSettings.PrintFileName = notExistingFileName;
    pdoc.PrinterSettings.PrintToFile = true;
    pdoc.PrintPage += pdoc_PrintPage;
    pdoc.Print();
 }
