PrintFileDocumentAdapter

public class PrintFileDocumentAdapter extends PrintDocumentAdapter
Adapter for printing PDF files. This class could be useful if you want to print a file and intercept when the system is ready spooling the data, so you can delete the file if it is a temporary one. To achieve this one must override {@link #onFinish()} and delete the file yourself.
