I've just had a little play with print api... here's a html printer class.  I still need to put a catch printer controller in because i almost wasted half a ream of paper! (doop)

public class print  {
   
    public static void main(String args[]) {
        print ps = new print();
    }
    public print() {
                /* Construct the print request specification.
                 * The print data is Postscript which will be
                 * supplied as a stream.  The media size
                 * required is A4, and 2 copies are to be printed
                 */
        //DocFlavor flavor = DocFlavor.INPUT_STREAM.TEXT_HTML_UTF_8;
       
        //DocFlavor flavor = DocFlavor.STRING.TEXT_HTML_UTF_8;
        DocFlavor flavor = DocFlavor.STRING.TEXT_HTML;
        //DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
        PrintRequestAttributeSet aset =
        new HashPrintRequestAttributeSet();
        aset.add(MediaSizeName.ISO_A4);
        aset.add(new Copies(2));
        aset.add(Sides.TWO_SIDED_LONG_EDGE);
        aset.add(Finishings.STAPLE);
       
        /* locate a print service that can handle it *//*
        PrintService[] pservices =
        PrintServiceLookup.lookupPrintServices(flavor, aset);*/
       
        System.out.println(PrintServiceLookup.lookupDefaultPrintService());
       

            DocPrintJob pj = PrintServiceLookup.lookupDefaultPrintService().createPrintJob();
            try {
 
                FileInputStream fis = new FileInputStream("c:\\test.html");
                Doc doc = new SimpleDoc(fis, flavor, null);                
               
                /* print the doc as specified */
                pj.print(doc, aset);
               

               
            } catch (IOException ie) {
                System.err.println(ie);
            } catch (PrintException e) {
                System.err.println(e);
            }

    }
}


// you'll have to change the flavor to pdf, rtf and play with their settings (to avoid invalid flavor
// errors)
Python 3 Fundamentals

This course will teach participants about installing and configuring Python, syntax, importing, statements, types, strings, booleans, files, lists, tuples, comprehensions, functions, and classes.

JPS is however a little buggy, or more correctly not mature yet (as you require a third party print service to use the pdf printing functions).

There is of course a much cleaner solution if you're deploying this application on windows.

This comes courtesy of the [chicks] from the p-pdf developers forum (i lost the original link so i'll post it here).

An example of viewing/printing PDF or other file types from Java on Windows.

Uses Windows ShellExecute function, with "print", "printto" or "open" verbs. ShellExecute will associate file with its viewer using the file's extension.

Viewers (Adobe Reader, Word, Excel, etc.) must be installed for this to work.

Extract ShellExec.dll from the attached jar to the current directory, then test with:

java -cp ShellExec.jar Test mypdf.pdf

Which will open "mypdf.pdf" in Adobe Reader. Change Test.java to "print" or "printto" to test printing.

You can download shellexec.jar from here
http://www.dmac.adelaide.edu.au/shellexec.jar

It's only temporary storage on our webserver, so i suggest you dl it soon.

Just a comment I'd like to add to this, it uses a dll written in c that accesses windows directly.  It is a prerequisite that adobe acrobat reader is installed to print pdf's , or word (or word viewer) is installed to print doc's.  But it's the simplest solution i've found so far that works.
