Hi,

I'm getting different results for the printable area for different
versions of java (running on Linux 2.6.17-1.2142_FC4). The code below
just gets the printable area for A4 landscape.

Using java version "1.5.0_09", I get:

(6.35,6.35)->(197.3,284.3)mm

This area is centred on A4 landscape paper, which is what I expect.

Using java version "1.6.0_07", I get:

(12.7,12.7)->(197.203,284.339)mm

Since A4 landscape is (297mm x 210mm), this means that the printable
area goes slightly off the edge of the paper. It seems the offset has
been doubled and the area has (very slightly) increased. I searched
the bug database, but couldn't find anything that matched (although
it's possible I may have missed something). Has anyone else come
across this? Both examples were run using the same printer and printer
driver.

import java.awt.print.*;
import javax.print.*;
import javax.print.attribute.*;
import javax.print.attribute.standard.*;

public class TestMediaPrintableArea
{
   public static void main(String[] args)
   {
      HashPrintRequestAttributeSet aset
         = new HashPrintRequestAttributeSet();

      aset.add(MediaSizeName.ISO_A4);
      aset.add(OrientationRequested.LANDSCAPE);

      PrintService[] services = PrinterJob.lookupPrintServices();

      if (services.length > 0)
      {
         MediaPrintableArea[] mpa = (MediaPrintableArea[])
            services[0].getSupportedAttributeValues(
               MediaPrintableArea.class,null,
               aset);

         for (int i = 0; i < mpa.length; i++)
         {
            System.out.println(mpa[i]);
         }
      }
   }
}
