Hi,

Thanks for your posting and using Spire.PDF.
Please refer to the following code.

Code: Select all

  string[] files = null;
            files = Directory.GetFiles("D:\\files", "*.pdf");
            foreach (string lcFile in files)
            {
                PdfDocument doc = new PdfDocument();
                doc.LoadFromFile(lcFile);
                PrinterSettings.PaperSourceCollection collections = doc.PrintDocument.PrinterSettings.PaperSources;
                List<PdfPaperSourceTray> loPaperSources = new List<PdfPaperSourceTray>();

                //Assume collections[2] is big A3,and collections[3] is A4.

                PdfPageBase loPage = doc.Pages[0];
                if (loPage.Size == PdfPageSize.A4)
                {
                    PdfPaperSourceTray tray = new PdfPaperSourceTray();
                    tray.StartPage = 0;
                    tray.EndPage = doc.Pages.Count - 1;
                    tray.PrintPaperSource = collections[3];
                    loPaperSources.Add(tray);
                }
                else   //A3
                {
                    PdfPaperSourceTray tray = new PdfPaperSourceTray();
                    tray.StartPage = 0;
                    tray.EndPage = doc.Pages.Count - 1;
                    tray.PrintPaperSource = collections[2];
                    loPaperSources.Add(tray);
                }
                doc.PageSettings.ListPaperSourceTray = loPaperSources;
                doc.PrintDocument.Print();
            }
