How to find out minimum margins for a printer?
Using J2SE 1.4 on Windows XP.
I want to find out the minimum margins for a printer. If I do this:
PrintService ps = ...;
PrinterJob job = PrinterJob.getPrinterJob ();
job.setPrintService (ps);
PageFormat pf = job.defaultPage ();
...then pf.getImageableX() and pf.getImageableY() return 72.0 for every printer I've tried!
On Windows, what I want is GetDeviceCaps (hDC, PHYSICALOFFSETX)
Can I get this data in Java?
Thanks

Just for reference, I believe I've found out how to do this. Not very intuitive, and I hope Sun will consider improving this next time 'round!
To determine the minimum margins on a printer, create a PrinterJob & set it to refer to the PrintService for the printer. Then execute some code like this:
PageFormat pf = job.defaultPage();
Paper paper = pf.getPaper();
paper.setImageableArea(0, 0, paper.getWidth(), paper.getHeight());
pf = job.validatePage(pf);
The Paper in the PageFormat now represents the maximum imageable area on the printer.
Even if Sun fixes defaultPage so that it returns a PageFormat in this state, this code will still work.
