The applets and applications they use may run in concert with a browser or directly on top of an operating system itself. In all cases, users expect to be able to print from their desktop to any printers on their network.

The Java environment must meet this need by providing a rich set of printing interfaces and functionality, including:. The original JDK 1. The release of the 1. JDK 1.

Note that this does not necessarily require that the printer be connected physically to the client machine, but rather that the Java client uses facilities provided by the platform operating system to use a printer.

Also note that some Java platforms may have no printer accessible, directly or indirectly. To print, a client initiates a print job by obtaining a new instance of PrintJob. The PrintJob class will create for you an instance of a concrete subclass of Graphics, which implements all the usual rendering calls for text, graphics, and images.

This subclass differs from the normal Graphics subclasses in that rendering is done not on the screen, but on a printer. In practice, the subclass either builds a document file, such as PostScript, and ships it to a printer, or it passes the responsibility on to the operating system, e. You indicate the end of each page by calling dispose on the Graphics subclass, and obtain a new graphics instance from PrintJob for the next page.

Java Printing SDK 1. Reference: SDK 1. The SDK 1. The Java printing system uses a callback model in which the printing system controls when pages are printed; the application provides information about the document to be printed, and the printing system asks the application to render each page as it needs them.

While untraditional, the callback model fits better with the existing AWT component painting model. The printing system might request that a particular page be rendered more than once or request that pages be rendered out of order. The application must be able to generate the proper page image, no matter which page the printing system requests. In this respect, the printing system is similar to the window toolkit, which can request components to repaint at any time, in any order.

The callback printing model is also more flexible than traditional application-driven printing models and supports printing on a wider range of systems and printers. For example, if a printer stacks output pages in reverse order, the printing system can ask the application to generate pages in reverse order so that the final stack is in proper reading order.An application invokes the static methods of the abstract class PrintServiceLookup to locate print services that have the capabilities to satisfy the application's print request.

For example, to print a double-sided document, the application first needs to find printers that have the double-sided printing capability. Attribute Definitions The javax. The javax. The attributes specified in javax. A DocFlavor object consists of a MIME type, which describes the format, and a document representation class name that indicates how the document is delivered to the printer or output stream.

An application uses the DocFlavor and an attribute set to find printers that can print the document type specified by the DocFlavor and have the capabilities specified by the attribute set. Creates a set of attributes. Locates a print service that can handle the print request as specified by the DocFlavor and the attribute set.

Gets a print job, represented by DocPrintJobfrom the print service. Calls the print method of the print job. The following code sample demonstrates a typical use of the Java Print Service API: locating printers that can print five double-sided copies of a Postscript document on size A4 paper, creating a print job from one of the returned print services, and calling print. A4 ; aset. Usage to the contrary is incorrect coding and may result in a run time exception either immediately or at some later time.

This interface represents a print job that can print a specified document with a set of job attributes. Interface FlavorException is a mixin interface which a subclass of PrintException can implement to report an error condition involving a doc flavor or flavors class DocFlavor.

Interface MultiDoc specifies the interface for an object that supplies more than one piece of print data for a Print Job. Obtained from a MultiDocPrintService, a MultiDocPrintJob can print a specified collection of documents as a single print job with a set of job attributes. Class DocFlavor encapsulates an object that specifies the format in which print data is supplied to a DocPrintJob.

Class DocFlavor. InputStream as the print data representation class. Reader as the print data representation class. String as the print data representation class. Implementations of this class provide lookup services for print services typically equivalent to printers of a particular type. This class is a collection of UI convenience methods which provide a graphical user dialog for browsing print services looked up through the Java Print Service API.

Services may optionally provide UIs which allow different styles of interaction in different roles. This class is an implementation of interface Doc that can be used in many common printing requests. This class extends PrintService and represents a print service that prints data in different formats to a client-provided output stream.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I'd be careful when using this approach for time-sensitive applications because internally get method is linearly searching O n for the corresponding value. The get method internally makes a call to getNode hash keykey which uses hashing. It does a linear search only when there is a hash collision. The Overflow Blog.

Socializing with co-workers while social distancing. Podcast Programming tutorials can be a real drag. Featured on Meta.A Printable. When the client subsequently initiates printing by calling PrinterJob. It does this by calling Printable. In using the Printable interface the printing commits to image the contents of a page whenever requested by the printing system. The parameters to Printable. For correct printing behaviour, the following points should be observed: The printing system may request a page index more than once.

On each occasion equal PageFormat parameters will be supplied. The printing system will call Printable. If multiple collated copies of a document are requested, and the printer cannot natively support this, then the document may be imaged multiple times.

Printing will start each copy from the lowest print stream page index page. With the exception of re-imaging an entire document for multiple collated copies, the increasing page index order means that when page N is requested if a client needs to calculate page break position, it may safely discard any state related to pages When called by the printing system the Printable must inspect and honour the supplied PageFormat parameter as well as the page index.

The format of the page to be drawn is specified by the supplied PageFormat. The size, orientation and imageable area of the page is therefore already determined and rendering must be within this imageable area.

This is key to correct printing behaviour, and it has the implication that the client has the responsibility of tracking what content belongs on the specified page. When the Printable is obtained from a client-supplied Pageable then the client may provide different PageFormats for each page index.

Calculations of page breaks must account for this. A PrinterJob calls the Printable interface to request that a page be rendered into the context specified by graphics.

The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException. Throws: PrinterException - thrown when the print job is terminated.

Implementations of this listener interface should be attached to a DocPrintJob to monitor the status of the printer job. These callback methods may be invoked on the thread processing the print job, or a service created notification thread. In either case the client should not perform lengthy processing in these callbacks.

Everything works fine. Now, I would like to be able to indicate that I want to print 2 pages per sheet. How can I do that? This content has been marked as final.

Show 11 replies. Are you talking about duplex printing or do want to print two logical pages upon one side of the paper?

The first is really a printer feature and I don't think you can do much about it, for the second, well, have your printables scale down and translate the printed content accordingly. Thanks for your answer, il will check right now the URLs you indicated. I want to be abble to print 2 pages on the front and back of a sheet paper So you want duplex printing.

Ok, in theory i found my solution, but it is not working. I want to print 1 page in each side of a sheet.
