Print pdf in network printer using java

Question

Guys I am stuck in printing a pdf using java. The code that I have written is below:

`

public static void main(String[] args) throws PrinterException, PrintException, IOException{
        DocFlavor docflavor = new DocFlavor.INPUT_STREAM ("application/octet-stream");
    //  DocFlavor docflavor = DocFlavor.SERVICE_FORMATTED.PAGEABLE;
/*      DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.;*/
        PrintService printService = PrintServiceLookup.lookupDefaultPrintService();
        DocFlavor[] docF = printService.getSupportedDocFlavors();
        for(int i = 0; i<docF.length;i++){
            System.out.println(docF[i]);
        }
        FileInputStream fis = new FileInputStream("pathofpdffile");



        Doc pdfDoc = new SimpleDoc(fis, docflavor, null);


        DocPrintJob printJob = printService.createPrintJob();
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

        aset.add(new Copies(1));
        aset.add(Sides.ONE_SIDED);
        printJob.print(pdfDoc,aset);

        fis.close();

}`

The above code intiate the printing activity but the problem is that I get only encode character in print. I am not able to get my exact file.

Second if I change the DocFlavor to SERVICE_FORMATTED.PAGEABLE ,it throws an error

java.lang.IllegalArgumentException: data is not of declared type
at javax.print.SimpleDoc.<init>(Unknown Source)
at com.calculator.main.PrintingTest.main(PrintingTest.java:42)

Third IF I change the DocFlavor to INPUT_STREAM.PDF, it throws as error

`Exception in thread "main" sun.print.PrintJobFlavorException: invalid flavor
at sun.print.Win32PrintJob.print(Unknown Source)
at com.calculator.main.PrintingTest.main(PrintingTest.java:49)`

All this I am trying on a network printer. Any help would gr8..

Answer 1

Just change your code to use AUTO_SENSE as shown below.

InputStream inputStream = new FileInputStream("C://test.pdf");
Doc doc = new SimpleDoc(inputStream, DocFlavor.INPUT_STREAM.AUTOSENSE,null);

Answer 2

My first guess would be that new DocFlavor.INPUT_STREAM ("application/octet-stream") isn't what you want.
