Orientation sets only for first page in PDF printing - java

Question

I'm using PDFRenderer.jar and this is the method i'm using to set print format,

private void initialize(byte[] pdfContent, String jobName) throws IOException, PrinterException {
        ByteBuffer bb = ByteBuffer.wrap(pdfContent);
        // Create PDF Print Page
        PDFFile pdfFile = new PDFFile(bb);
        PDFPrintPage pages = new PDFPrintPage(pdfFile);

        // Create Print Job
        pjob = PrinterJob.getPrinterJob();
        PageFormat pf = PrinterJob.getPrinterJob().defaultPage();

        pf.setOrientation(PageFormat.PORTRAIT);
        pjob.setJobName(jobName);

        Book book = new Book();
        book.append(pages, pf, pdfFile.getNumPages());
        pjob.setPageable(book);

//         to remove margins
        Paper paper = new Paper();
        paper.setSize(paper.getWidth(), paper.getHeight());
        paper.setImageableArea(0, 0, paper.getWidth(), paper.getHeight());

        pf.setPaper(paper);
    }

The issue is, orientation PORTRAIT sets only to the first page of the pdf,second page comes in REVERSE_LANDSCAPE which I haven't set from the code.

Any ideas?

Finaly , I found it

We cannot set print formats only from setting attributes to java.awt.print.PageFormat , we have to overide print(Graphics g, PageFormat format, int index) method in java.awt.print.Printable.This make the file print in pdf format(text and alignments).

Therefore this is the overridden print method,

  public int print(Graphics g, PageFormat format, int index) throws PrinterException {
        int pagenum = index + 1;
        if ((pagenum >= 1) && (pagenum <= file.getNumPages())) {
            Graphics2D g2 = (Graphics2D) g;
            PDFPage page = file.getPage(pagenum);

            // fit the PDFPage into the printing area
            Rectangle imageArea = new Rectangle((int) format.getImageableX(), (int) format.getImageableY(),
                    (int) format.getImageableWidth(), (int) format.getImageableHeight());
            g2.translate(0, 0);
            PDFRenderer pgs = new PDFRenderer(page, g2, imageArea, null, null);
            try {
                page.waitForFinish();
                pgs.run();
            } catch (InterruptedException ie) {
                // nothing to do
            }
            return PAGE_EXISTS;
        } else {
            return NO_SUCH_PAGE;
        }
    }

So,here is full code for print pdf (for printers doesn't support direct printing) using pdf renderer,

    public static void main(String[] args) throws IOException, PrinterException {
    if (args.length != 1) {
        System.err.println("The first parameter must have the location of the PDF file to be printed");
    }

    FileInputStream fis = new FileInputStream(new File("x.pdf"));//file path

    PrintPdf printPDFFile = new PrintPdf(fis, "Test Print PDF");
    printPDFFile.print();
}

public static PrintService setPrintService(String argPrintServiceName) throws PrinterException {
    PrintService psr = null;
    PrintService[] printServices = PrinterJob.lookupPrintServices();
    int i;
    for (i = 0; i < printServices.length; i++) {
        if (printServices[i].getName().equalsIgnoreCase(argPrintServiceName)) {
            psr = printServices[i];
            break;
        }
    }
    if (i == printServices.length) {
        throw new PrinterException("Invalid print service name: " + argPrintServiceName);
    }
    return psr;
}

/**
 * Constructs the print job based on the input stream
 *
 * @param inputStream
 * @param jobName
 * @throws IOException

 */
public PrintPdf(InputStream inputStream, String jobName) throws IOException, PrinterException {
    byte[] pdfContent = new byte[inputStream.available()];
    inputStream.read(pdfContent, 0, inputStream.available());
    initialize(pdfContent, jobName);
}

/**

 *

 */
private void initialize(byte[] pdfContent, String jobName) throws IOException, PrinterException {
    ByteBuffer bb = ByteBuffer.wrap(pdfContent);
    /* Create PDF Print Page*/
    PDFFile pdfFile = new PDFFile(bb);
    PDFPrintPage pages = new PDFPrintPage(pdfFile);

    /* Create Print Job  */
    pjob = PrinterJob.getPrinterJob();
    pf = PrinterJob.getPrinterJob().defaultPage();

    pf.setOrientation(PageFormat.PORTRAIT);
    pjob.setJobName(jobName);

    Book book = new Book();
    book.append(pages, pf, pdfFile.getNumPages());
    pjob.setPageable(book);

    /* to remove margins  */
    Paper paper = new Paper();
    paper.setImageableArea(0, 0, paper.getWidth(), paper.getHeight());

    pf.setPaper(paper);
}

public void print() throws PrinterException {
    // Send print job to default printer
    pjob.print();
}

/**
 * Class that actually converts the PDF file into Printable format

class PDFPrintPage implements Printable {

    private PDFFile file;

    PDFPrintPage(PDFFile file) {
        this.file = file;
    }

    public int print(Graphics g, PageFormat format, int index) throws PrinterException {
        int pagenum = index + 1;
        if ((pagenum >= 1) && (pagenum <= file.getNumPages())) {
            Graphics2D g2 = (Graphics2D) g;
            PDFPage page = file.getPage(pagenum);

            // fit the PDFPage into the printing area
            Rectangle imageArea = new Rectangle((int) format.getImageableX(),(int)format.getImageableY(),(int) format.getImageableWidth(), (int) format.getImageableHeight());
            g2.translate(0, 0);
            PDFRenderer pgs = new PDFRenderer(page, g2, imageArea, null, null);
            try {
                page.waitForFinish();
                pgs.run();
            } catch (InterruptedException ie) {
                // nothing to do
            }
            return PAGE_EXISTS;
        } else {
            return NO_SUCH_PAGE;
        }
    }

}

Thanks if any one who tried to find the bug and my senior engineer for giving his support to find this.
