Printing function gets called twice..!

Question

The following is my class that prints a string array which sometimes goes into multiple pages.. The code in which i create the multiple pages is below this class.. the problem is each time i append a new page to the book the print function in the class PaintC is called twice.. so if I write some additional code inside the print function to edit the strings .. it ends up running twice and the formatting i try to do gets messed up.. !! do you guys know why this is happening..? Please help.. ive been trying to find out since a very long time..!!
The code in which i call this function is also shown below
CLASS FOR PRINTING
class PaintC
    implements Printable {
  String ad[];
  public PaintC(String ac[]) {
    System.out.println("Print Class Called 1");
    this.ad = ac;
  public int print(Graphics g, PageFormat pf, int pageIndex) throws
      PrinterException {
    System.out.println("Print Function Called 1");
    Graphics2D g2 = (Graphics2D) g;
    g.setFont(new java.awt.Font("Trebuchet MS", Font.PLAIN, 8));
    int xo = 60;
    int yo = 36;
    for (int y = 0; y < 76; y++) {
      try {
        g2.drawString(ad[y], xo, yo);
        yo += 9;
      catch (Exception r) {
        y = 76;
    return Printable.PAGE_EXISTS;
CODE FOR CREATING MULTIPLE PAGES USING ABOVE CLASS
void dotheprint() {
    PrinterJob printerJob = PrinterJob.getPrinterJob();
    PageFormat format = new PageFormat();
    Printable painter1;
    format = printerJob.defaultPage(format);
    Paper paper = format.getPaper();
    paper.setImageableArea(60, 36, 500, 756);
    format.setPaper(paper);
    // try storing in a string array each line
    Book bk = new Book();
    String ab = jTATRRep.getText();
    int i, j, lc = jTATRRep.getLineCount();
    String ac[] = new String[lc + 3];
    String ad[] = new String[78];
    ac = ab.split("\n");
    //System.out.println("Number of Lines = " + lc);
    //setting up pages as string arrays..
    // setting up first page
    //Assuming 76 lines per page
    for (i = 0; i < 76 && i < lc; i++) {
      try {
        ad[i] = ac;
catch (Exception ex) {
bk.append(new PaintC(ad), format);
ad = null;
// setting up second page if neccessary
// //System.out.println("Number of Lines /76= "+lc/76);
int pagec = lc / 76;
int modul = lc % 76;
int k;
if (modul > 0) {
pagec++;
// //System.out.println("Number of pages : "+pagec);
j = 76;
while (pagec > 1) {
ad = new String[76];
k = 0;
for (i = j; i < (lc - 1) && k < 76; i++) {
// //System.out.println("ac[i]= "+ac[i]);
ad[k] = ac[i];
k++;
bk.append(new PaintC(ad), format);
ad = null;
j += 76;
pagec--;
printerJob.setPageable(bk);
boolean doPrint = printerJob.printDialog();
if (doPrint) {
try {
System.out.println("Print Called 1");
printerJob.print();
System.out.println("Print Called 2");
catch (PrinterException exception) {
System.err.println("Printing error: " + exception);
CODE IN WHICH THE PRINT FUNCTION IS CALLED
void jBPrint_actionPerformed(ActionEvent e) {
    dotheprint();
class ContactManager_jBPrint_actionAdapter
    implements java.awt.event.ActionListener {
  ContactManager adaptee;
  ContactManager_jBPrint_actionAdapter(ContactManager adaptee) {
    this.adaptee = adaptee;
  public void actionPerformed(ActionEvent e) {
    adaptee.jBPrint_actionPerformed(e);
