How do I get printer margins and resolution

Question

How do I get printer margins and dots per inch for the so-called default printer that is attached to my computer (and possible the less critical paper size)

Answer 1

Thanks for your trying it. I learned from you that prinJob.pageDialog() sees the physical limitations on the margins.
I found in the docs: "When creating a Paper object, it is the application's responsibility to ensure that the paper size and the imageable area are compatible".
It seems that most of this stuff is the program telling the printer.
I want the printer to tell the program two critical sets of data: the minimum margins and the resolution.
Thanks again, I really appreciate your efforts, and learning one more thing.
Here is my try. Sorry about the long lines.
    PrinterJob prinJob=PrinterJob.getPrinterJob();
    PageFormat pgFmt = prinJob.defaultPage();       
    System.out.println("old iW="+pgFmt.getImageableWidth()+" iH="+pgFmt.getImageableHeight()+" iY="+pgFmt.getImageableX()+" iX="+pgFmt.getImageableY());
    PageFormat newPgFmt = prinJob.pageDialog(pgFmt); //min: l=.226(16.272pt),r=.273,t=.25(18pt),b=.25 so wid=8.0(576pt), hgt=10.5(756pt)
    System.out.println("new iW="+newPgFmt.getImageableWidth()+" iH="+newPgFmt.getImageableHeight()+" iY="+newPgFmt.getImageableX()+" iX="+newPgFmt.getImageableY());
    Paper pap = newPgFmt.getPaper(); //pageDialog() seems to get the physical printer correctly approx agreeing with MSWord
    System.out.println("pap wid="+pap.getWidth()+" hgt="+pap.getHeight()+" iX="+pap.getImageableX()+" iY="+pap.getImageableY()+" iW="+pap.getImageableWidth()+" iH="+pap.getImageableHeight());
    pap.setImageableArea(0,0,72*8.5,72*11.0); //this allows programmer to set it incorrectly
    System.out.println("pap wid="+pap.getWidth()+" hgt="+pap.getHeight()+" iX="+pap.getImageableX()+" iY="+pap.getImageableY()+" iW="+pap.getImageableWidth()+" iH="+pap.getImageableHeight());
    newPgFmt.setPaper(pap);
    System.out.println("new iW="+newPgFmt.getImageableWidth()+" iH="+newPgFmt.getImageableHeight()+" iY="+newPgFmt.getImageableX()+" iX="+newPgFmt.getImageableY());
