[Example 9] Print PDF for one page, multiple pages, multiple pages are one page

【Example 10】Custom paper size print PDF

1. Customize paper size printing with a virtual printer: Keep the original page size printed to PDF

//Load the PDF document that needs to be printed doc = new ();
(FileName);

//Get the paper size of the first page of the original document, the unit here is PointSizeF size = [0].Size;

//Instantiate the PaperSize object and set its width and height//It should be noted that the unit conversion is involved. The default unit of PaperSize's width and height parameter is 100 inchesPaperSize paper = new PaperSize("Custom", (int)/72*100, (int)/72*100);
 = (int);

//Set the printed paper size to the original document size = paper;

//FitSize printing mode needs to be selected(, true);
//Print();

2. Use the real printer to set the paper size in the paper tray to print: Print the original A4 document to the size of A3.

//Load the PDF document that needs to be printed  doc = new ();
 (FileName);

 PaperSize p = null;
 //Instantiate a PrintDocument object to get the current printer's tray information PrintDocument printDoc = new PrintDocument();

 //Travel through the paper inside the printer paper tray and find the required A3foreach (PaperSize ps in )
      {
        if (("A3"))
        {
          p = ps;
          break;
        }
        
      }
