public class PrintPdfPages
extends Object

PrintPdfPages

This class provides a simple Java API to access PDF printing features in JPEDAL via a simple API

Example 1 - Print all pages from a PDF

PrintPdfPages print=new PrintPdfPages("C:/pdfs/mypdf.pdf");
      //print.setPassword("password");
      if (print.openPDFFile()) {
          print.printAllPages("Printer Name");
      }

      print.closePDFfile(false);

Example 2 - Print a single page from a PDF

PrintPdfPages print=new PrintPdfPages("C:/pdfs/mypdf.pdf");
      //print.setPassword("password");
      if (print.openPDFFile()) {
          int pageNumber = 1;
          print.printPage("Printer Name", pageNumber);
      }

      print.closePDFfile(false);

Example 3 - Access directly from the Jar

PrintPdfPages can run from jar directly using the command and will print pages from a PDF file.

java -cp libraries_needed org/jpedal/examples/printing/PrintPdfPages inputValues

Where inputValues is 2 or 3 values:

• First value: The PDF filename (including the path if needed). If it contains spaces it must be enclosed by double quotes (ie "C:/Path with spaces/").
• Second value: The name of the printer to be used. If it contains spaces it must be enclosed by double quotes (ie "My Printer").
• Third value: The page number you wish to print as an integer. This is optional, if not set all pages are printed.

See our Support Pages for more info on PDF printing.
When running on Windows, Win32PrintServiceLookup starts a daemon thread that does not close when all threads have ended. In order to prevent this thread remaining open and keeping the application open either System.exit(0) should be called or the final use of the method closePDFfile(boolean closeAllThreads) should have an input of true.

closePDFfile

public void closePDFfile(boolean closeAllThreads)

Ensure PDF file is closed once no longer needed and all resources released.
Please note, Win32PrintServiceLookup used by Java on Windows has a daemon thread that doesn't close. In order to close this thread a System.exit(0) is required to close the application otherwise the thread prevents it from closing.

Parameters:

closeAllThreads - Flag to call System.exit(0) when finished
