  I am attempting to print out 4 segments of text:
    "package", " ", "myfirstpackage1", ";"
  (minus quotes and separators) on the same line, font size,
  and font style, but am not able to get the alignment of the
  text correct. In certain font sizes, the final semicolon (;)
  ends up overwriting the last part of "myfirstpackage1".
    My sample program draws each run of text using
  graphics.drawString(...), and computes the x-position for
  the next run of text using fontMetrics.stringWidth(). I
  have also tried fontMetrics.getStringBounds(...), but that
  makes no difference.
    I have included a sample program which puts up a JFrame
  of the text I am trying to print, followed by a print job
  submission. The output on the screen is correctly aligned,
  but the printed output is mis-aligned.

Impact:
  With the misalignment, certain fonts and/or sizes do not
  print out correctly from the code editor in
  Oracle JDeveloper 9i, so this bug has a visible product
  impact. There appears to be no workaround for this problem.

Environment:
  Compaq Armada M700, 850Mhz, 448MB RAM
  Windows XP Professional w/ SP1
  JDK 1.3:
    java version "1.3.1"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
    Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)
  Using XP drivers for HP DeskJet 895cxi

  Print Server:
    Dell Optiplex GX1, 400 MHz, 384MB RAM
    Windows 2000 Server w/ SP2
    HP DeskJet 895cxi

Workaround:
  None, assuming my code is written correctly.

Testcase:
import java.awt.*;
import java.awt.print.*;
import javax.swing.*;

public class PrintTest extends Canvas implements Printable
{
  public void paint( Graphics graphics )
  {
    // This will print 12 lines containing:
    // package mypackage1;
    // with the respective font styles per size/line
    String[] STRINGS = new String[]
    {
      "package",
      " ",
      "myfirstpackage1",
      ";"
    };
    int[] STYLES = new int[]
    {
      Font.PLAIN,
      Font.PLAIN,
      Font.PLAIN,
      Font.PLAIN
    };
    int[] SIZES = new int[]
    {
      5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
    };

    graphics.setColor( Color.black );
    int yPos = 0;
    for ( int i = 0; i < SIZES.length; i++ )
    {
      int size = SIZES[i];
      
      int xPos = 0;
      for ( int j = 0; j < STRINGS.length; j++ )
      {
        String string = STRINGS[j];
        int style = STYLES[j];

        Font font = new Font( "DialogInput", style, size );
        FontMetrics metrics = graphics.getFontMetrics( font );
        graphics.setFont( font );

        int fontAscent = metrics.getAscent();
        graphics.drawString( string, xPos, yPos + fontAscent );

        xPos += metrics.stringWidth( string );
      }

      // After each line, advance the yPos - just use the last metrics
      // we drew with
      FontMetrics lastMetrics = graphics.getFontMetrics();
      int fontHeight = lastMetrics.getHeight();
      yPos += fontHeight;
    }
  }

  public int print( Graphics graphics, PageFormat pageFormat, int pageIndex )
throws PrinterException
  {
    if ( pageIndex != 0 )
    {
      return NO_SUCH_PAGE;
    }

    int visibleX = (int) pageFormat.getImageableX();
    int visibleY = (int) pageFormat.getImageableY();
    graphics.translate( visibleX, visibleY );
    paint( graphics );

    return PAGE_EXISTS;
  }


  public static void main( String[] args )
  {
    JFrame frame = new JFrame( "Print Test" );
    frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
    PrintTest painter = new PrintTest();
    frame.getContentPane().add( painter );
    frame.setSize( 800, 700 );
    frame.setVisible( true );

    try
    {
      PrinterJob job = PrinterJob.getPrinterJob();
      job.setPrintable( painter );
      if ( job.printDialog() )
      {
        job.print();
      }
    }
    catch( PrinterException e )
    {
      System.out.println( "print error: " + e );
    }
  }
}
