Why doesn't the line break change w/font size??

Question

Hello,
I am trying to print out a simple paragraph (String object) to the printer. I am trying to get the text to wrap properly based on font size. I've search on the posts and can't find the answer.
It looks like the LineBreakMeasurer is only working with default font size? No matter what font I use in the graphics, the string always seems to break in the same column? Any ideas?
Here is a sample of the code I'm using.
Note - the actual printing (draw) is commented out.)
Thanks,
Jim

Just for everyone elses reference, below is the modified code that works for me.
<pre>
import java.awt.*;
import java.awt.print.*;
import java.text.*; //for AttributedCharacter
import java.awt.font.*; //for FontRenderContext
import java.util.*;
import javax.swing.*;

String textToPrint;
AttributedString as;
AttributedCharacterIterator aci;
Font font = new Font("Arial", Font.PLAIN, 18);
//Font font = new Font("TimesRoman", Font.PLAIN, 8);
public PrintTest3(String text) {
//text represents one paragraph of text
textToPrint = text;
as = new AttributedString(textToPrint);
aci = as.getIterator();
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(this);
if (job.printDialog() ) {
try {
job.print();
catch(Exception e) {
e.printStackTrace();
public static void main(String args[]) {
String testMsg = new String("TEST TEST TEST - The quick brown fox jumped over the lazy dogs back. " +
"How now brown cow? This will be a fairly long line so I can see how the text will wrap " +
"around on the printer when it prints. This is the end of the test string.\n");
PrintTest3 tp = new PrintTest3(testMsg);
System.exit(0);
public int print(Graphics g, PageFormat pf, int idx) {
if (idx > 0){
return Printable.NO_SUCH_PAGE;
Graphics2D g2d = (Graphics2D)g;
g2d.setFont(font);
as.addAttribute(TextAttribute.FONT, font);
float xo = (float)pf.getImageableX();
float yo = (float)pf.getImageableY();
int y = font.getSize();
//aci is the AttributedCharacterIterator
LineBreakMeasurer measurer = new LineBreakMeasurer(aci, g2d.getFontRenderContext());
float wrappingWidth = (float)pf.getImageableWidth();
while (measurer.getPosition() < aci.getEndIndex() ) {
String printLine = textToPrint.substring(measurer.getPosition(), measurer.nextOffset(wrappingWidth) );
measurer.setPosition(measurer.nextOffset(wrappingWidth));
g2d.drawString(printLine, xo, y + yo);
y += font.getSize();
return Printable.PAGE_EXISTS;
