I created a class to print a PDF file.
The class opens a application window with a start button.
When the start button is clicked it opens a ProgressMonitorDialog that runs my PrintFile Class that allows the users to select a local printer and sends the printjob to my print method.
Everything runs correctly but the printjob is never sent to the printer.
I know that is gets past the print call
try {
System.out.println("before\n");
pjob.print();
System.out.println("after\n");
}
But the print method is never executed? So I am not sure what pjob.print(); is doing.

I feel like I am missing something simple, but have no clue what it is?
I am really stuck on this issue and really need help to figure this out.
Thanks to all that can help me
EDIT If I comment out the following code
if (pjob.printDialog()) {
The print comes right out!
But when it is not commented out, the printer selection dialog opens, click the OK button, printer dialog closes and nothing ever happens
EDIT
After some testing, I have discovered the problem has something with the pjob.printDialog().
I removed the if statment and set it up like this.
boolean ok = pjob.printDialog();
System.out.println("OK value " + ok + "\n");
//if (ok) {
pfDefault = pjob.validatePage(pfDefault);
Book book = new Book();
book.append(pages, pfDefault, pdfFile.getNumPages());
System.out.println("Print Job After : " + pjob + "\n");
pjob.setPageable(book);
try {
pjob.print();
}
catch (PrinterException e) {
e.printStackTrace();
}
printDialog opens, I click OK - A print job is sent to the printer, but nothing prints out. I click cancel - The print job is printed out as wanted
