JAVA SIMPLEDOC PRINT PDF

Kijinn Be sure to empty the print queue first. I have a program jzva printing a pdf file that was generated using the iText 2 package. The Doc implementation is required to support this method if the DocFlavor has one of the following print data representation classes, and return null otherwise: I just checked your code here at my place. Another possibility is that your drivers are out of date. Or just to be able to print?

Tweet Printing services is an important facility provided by any application programming framework. Java initially did not provide any such facility during its inception. But, in the later versions such as in 1. Versions prior to this had no such support. By printing service, we mean the APIs related to the use of a printer to be specific. The PrintJob class of the java. It was a very crude implementation and was never liked by the programmers.

Java 1. The principal class that controls all printing in this mechanism is the PrinterJob. This mechanism is still supported, including the PrintJob implementation of version 1. Java printing services gets a real accolade of reliability only from Java 1. However, there were still problems with these classes: PrintJob from Java version1. Firstly, both classes uses java.

Graphics to render the content of printing. This means that anything that needs to be printed first must be rendered into a graphical image. This is clearly an inefficient technique. Secondly, there is hardly any support for setting attributes related to printing. There is no support to dynamically select the printer.

Apart from these, it creates confusion due to the availability of so many printing facilities. It addressed these issues and resolved the problems with a revamped API. In addition to the introduction of new functionalities, the new APIs provide all the functionalities of the old print services as well.

Therefore, it is recommended that programmers use new printing APIs instead of old ones unless there is a specific need. Java Print Services At the outset of using print services in a Java application, we first need to locate a printer. This can be done by invoking the static method called lookupDefaultPrintSetrvice defined in the PrintServiceLookup abstract class.

But, the problem is that here we are assuming that the printer will be able to print the output correctly by selecting the platform native default print service rather than the one specific printer installed. It gives no choice to select the printer that supports application-specific needs. Therefore, to find out all the print services available, we may use one of two other alternative static functions defined in the PrintServiceLookup class, such as: public static final PrintService [] lookupPrintServices DocFlavor flavor, AttributeSet attributes public static final PrintService [] lookupMultiDocPrintServices DocFlavor flavor, AttributeSet attributes The parameter instance DocFlavor specifies the format of data to be supplied for printing, such as MIME type and the name of the representation class.

The AttributeSet specifies the attributes related to printing, such as color, orientation, double-sided printing, and so forth. The ServiceUI class provides a method called printDialog , which can be invoked to show the print dialog.

The user can choose the appropriate print service from there. The DocPrintJob is an interface that is used to control and monitor the status of the printing operation with a set of attributes defined by the PrintRequestAttributeSet object. Suppose we want to print a PDF file in the local machine; we may do it in the following manner: package org.

FileInputStream; import java. IOException; importjavax. Copies; import javax. If the printer is unable to print the flavor of document we want to print, the preceding code may throw an exception. The status of the print operation is monitored by implementing PrinJobListener. Here, we have implemented only two events. Other listeners are like, printJobCanceled , printJobFailed , and so on.

But, to begin with, this can be a starting point. There are deeper things associated with setting up the printer with various attributes. Refer to the Java API documentation to get finer detail on those aspects. Many of the relevant class explanations are overlooked to keep things simple. Also, one of the most interesting aspects of using the Java Print Service APIs is that we can control the formatting of the print.

This is a bit complex to begin with.
