Printing HTML file in java
I am trying to print the HTML file that my program generates, but it doesn't work. On Ubuntu ".isSupported (Desktop.Action.PRINT)" returns false even though I have gnome libraries installed and on Windows 7 java throws the following exception:
java.io.IOException: Failed to print file:/C:/Users/user/Documents/document.html. Error message: Unspecified error
followed by a stack. Below is the code, I am using java.awt.Desktop.
File doc = DocumentComposer.writeDocument(new File(System.getProperty("user.dir") + File.separator + "docs" + File.separator + docName + ".html"), case, data);
if (Desktop.isDesktopSupported())
{
Desktop desktop = Desktop.getDesktop();
if (desktop.isSupported(Desktop.Action.PRINT))
{
desktop.print(doc);
}
else
printError();
}
else
printError();
Any help would be much appreciated :).

I ended up not using java.awt.Desktop, it just didn't work. Instead, I followed the instructions in this IBM tutorial, http://www.ibm.com/developerworks/java/library/j-mer0322/ . To be precise, the code I'm currently using is the following (and it works flawlessly on Linux and Windows!):
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService service = ServiceUI.printDialog(GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration(), 200, 200,
printService, defaultService, flavor, pras);
if (service != null) {
DocPrintJob job = service.createPrintJob();
FileInputStream fis = new FileInputStream(doc);
DocAttributeSet das = new HashDocAttributeSet();
Doc document = new SimpleDoc(fis, flavor, das);
job.print(document, pras);
}
