Unwanted margins when printing images

Question

All,
I have an application that loads images from a chosen directory and loads them into tabs. I then have print options. All is fine printing however there is a 1" border around the image. This seems to squish the image smaller which results in more difficulty reading.
I have aquired a PrintImage class for GIF's somewhere from the Sun site and modified it to also accept JPG and PNG. Can anyone give an idea on how set the margin attributes from this code?
public class PrintImage {
    public void PrintImage(String path, String type) {
        /* Use the pre-defined flavor for a GIF from an InputStream */
        DocFlavor flavor = null;
        if (type.equals("gif")) {
            flavor = DocFlavor.INPUT_STREAM.GIF;
        } else if (type.equals("jpg") || type.equals("jpeg")) {
            flavor = DocFlavor.INPUT_STREAM.JPEG;
        } else if (type.equals("png")) {
            flavor = DocFlavor.INPUT_STREAM.PNG;
        /* Create a set which specifies how the job is to be printed */
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        aset.add(MediaSizeName.NA_LETTER);
        aset.add(new Copies(1));
        /* Locate print services which can print a GIF in the manner specified */
        PrintService[] pservices =
                PrintServiceLookup.lookupPrintServices(flavor, aset);
        if (pservices.length > 0) {
            /* Create a Print Job */
            DocPrintJob printJob = pservices[0].createPrintJob();
            /* Create a Doc implementation to pass the print data */
            Doc doc = new InputStreamDoc(path, flavor);
            /* Print the doc as specified */
            try {
                printJob.print(doc, aset);
            } catch (PrintException e) {
                System.err.println(e);
        } else {
            Component frame = null;
            JOptionPane.showMessageDialog(frame,
            "No suitable printers.",
            "Print error",
            JOptionPane.ERROR_MESSAGE);
    public static void main(String args[]) {
class InputStreamDoc implements Doc {
    private String filename;
    private DocFlavor docFlavor;
    private InputStream stream;
    public InputStreamDoc(String name, DocFlavor flavor) {
        filename = name;
        docFlavor = flavor;
    public DocFlavor getDocFlavor() {
        return docFlavor;
    /* No attributes attached to this Doc - mainly useful for MultiDoc */
    public DocAttributeSet getAttributes() {
        return null;
        /* Since the data is to be supplied as an InputStream delegate to
         * getStreamForBytes().
    public Object getPrintData() throws IOException {
        return getStreamForBytes();
    /* Not possible to return a GIF as text */
    public Reader getReaderForText()
    throws UnsupportedEncodingException, IOException {
        return null;
        /* Return the print data as an InputStream.
         * Always return the same instance.
    public InputStream getStreamForBytes() throws IOException {
        synchronized(this) {
            if (stream == null) {
                stream = new FileInputStream(filename);
            return stream;
}

To set a custom margin, you need to create a custom paper size. To do this, go into Page Setup, and under Paper Size choose Manage Custom Sizes. In the new dialog, click the plus sign at the bottom left to create a new size. Set the paper size to whatever you want (it should be 8.5X11" for letter, of course), and then set the margins to the size you need. Once you click the OK button, this paper size will now be available to choose in the Page Setup dialog.
