![]() ![]() The PrintGraphics doesn't know in advance if a page has transparency, so printing Handles this by rasterizing the page to a bitmap and including that bitmap in the Operations (like transparency) can't be done in PostScript, and the Java print layer It can represent text, vector graphics and images, so if your PDF containsĪ vector shape it's going to be reproduced almost exactly in PostScript. PostScript is the grandaddy of PDF, and if you're reading about printing you've already Suitable for printing, and in practice that means PostScript. This Graphics object will convert our graphics operations to a format Printable has a single print method which is given a Graphics2D object implementing PrinterGraphics, and our PDF API simply "draws" the PDF to that Graphics object, as if we were rendering The first thing that happens is our Pageable object is asked for a sequence of Printable objects, which represent a single page. Run as expected you'll need to peek behind the curtain to know why. Nine times out of ten that's all you'll need to know, but if your print job doesn't Here's how to print to our double-sided printer:ĭocumentAttributeSet datts = new HashDocumentAttributeSet() ![]() The PAGEABLE flavor so we need to pass in a Pageable object - this is the PDFParser object, which implements Pageable. How you specify the document depends on what sort of "flavor" you specified. It's double-sided, which pages to print and so on. Just like the PrintRequestAttribute helps to specify the type of printer you're looking for, the DocAttribute specifies details about the print job itself - the name of the the printjob, whether Now we need to specify the document and the job attributes. PrinterJob job = PrinterJob.getPrinterJob() Throw new IllegalStateException("No Printer found") PrintService ps = PrintServiceLookup.lookupPrintServices(flavor, patts) PrintRequestAttributeSet patts = new HashPrintRequestAttributeSet() Here's what the code would look like if we were looking for a printer thatĭocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE You also get to specify a set of PrintRequestAttributes to qualify your search for a printer - for instance, you may need a printer thanĬan print double-sided or that can print to A3, and there are attributes for each In the case of a PDF it's a PAGEABLE object, which means that the contents are a (potentially) multi-page object which ![]() In order to chose a printer you must first know what you're printing, which meansĬhoosing a DocFlavor. All the code below assumes you've imported, javax.print and its sub-packages. In Java is like printing any other type of document, but we'll go through all the Of these steps, the only PDF-specific one is the last, so in practice printing a PDF Assign the PDF and the attributes for this print job, then print.Create a PrinterJob and assign it to this service.Search for and select a PrintService to print to.To print a PDF from Java the process broadly works as follows: The packages for printing are the and javax.print packages - the latter dates from Java 1.4 and supplements, rather than replaces, ![]() In Java 5 and 6 printing is one area where a newer version of Java does help. Thankfully the API is now fairly stable, although fixes were made Toolkit method in Java 1.0 to the PrinterJob of Java 1.2 and the current PrintService approach in 1.4. It's not the most elegantĪspect of the language, which reflects it's evolution over the years from a single Printing has been possible since the beginnings of Java. ![]()
