Class PCLPrintJob

java.lang.Object
  com.openpcl.viewer.printing.PCLPrintJob

All Implemented Interfaces:

ImageObserver, Pageable, Printable

public class PCLPrintJob
extends Object
implements Pageable, Printable, ImageObserver

The purpose of this class is to handle the printing of a PCL bytestream to the printer, whether it uses PCLDirect or GDI. PCLDirect is the fastest but requires the printer selected to handle PCL 5 or higher. GDI is compatible with all printers but is slower since each page must be rendered before being sent to the printer.

DocMagic, Document Systems Inc, Jim Gabriel. Sept 18, 2007 9/18/07 to 9/25/07 Howard Hoagland. Changed significantly to make it work with OpenPCLViewer and PosPrintPages so that printing PCL Direct and Windows Print uses this class only and doesn't use PosPrintBufferedImage and PosPrintPageableInterface, because this class implements the methods of both those Interfaces and in fact the code from those two classes was cut and pasted into this class to make it do the job of those two. The main benefit of this class is to implement printing duplex for Windows Print. Helpful reference URLs used to create and design this class
