FULL PRODUCT VERSION :
java version "1.5.0-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-rc-b63)
Java HotSpot(TM) Client VM (build 1.5.0-rc-b63, mixed mode)

java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows XP Version 5.1.2600

A DESCRIPTION OF THE PROBLEM :
Java Print to 2D Stream does not work as expected for paper sizes other than A4.

If I print the imageableWidth and ImageableHeight of PageFormat, the numbers are the same for A3 and A4 pages, although the result is shifted, and the page dimensions only change for A2 and lower. What gets printed is far away from the range given by the numbers in PageFormat



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

Start with the example in:

http://java.sun.com/j2se/1.5.0/docs/guide/jps/spec/appendix_2DtoStream.fm.html

After
  ---- PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

insert
   ---- aset.add(MediaSizeName.ISO_A2); // or A0, A3, etc.

After
 --- public int print(Graphics g,PageFormat pf,int pageIndex) {

insert:
  --- System.out.println("Page dimensions in points inch-width:" + pf.getImageableWidth()/72 + " inch-height:" + pf.getImageableHeight()/72);



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Print2DtoStream example is, I believe, supposed to produce a 200 x
200 point = 2.7 x 2.7 inch black rectangle in the top left hand corner
of the page (leaving a margin) in the postscript image for all sizes.
This black square and example text to be visible in the postscript result no matter what the paper size.

Furthermore, page dimensions to vary with the different page sizes (see http://www.cl.cam.ac.uk/~mgk25/iso-paper.html)

The standard should be:

A4: 210 Èù 297 mm = 8.26 x 11.69 inches
A3: 297 x 420 mm = 11.69 x 16.53 inches
A2: 420 x 594 mm = 16.53 x 23.38 inches

The imageable area may be slightly smaller due to page margins.

ACTUAL -
For ISO_A4 I get
    inch-width=6.5 inch-height=9.0
For ISO_A3 I get
   inch-width=6.5 inch-height=9.0
For ISO_A2 I get
   inch-width=14.5... inch-height=21.3...

And the Black Square does not appear in the A0-A3 cases.


REPRODUCIBILITY :
This bug can be reproduced always.
