Hi Phil:
I tried out your suggestion ... I wrote a simple test program to determine
my default resolution. The program is attached. The first time I ran it, I
got 600 dpi, which is the default when the print dialog box comes up.
Thereafter, I am getting 72 dpi. I also tried enabling the print dialog box
in this Java program (i.e., uncomment out the commented lines), to see if
the resultion I get is what I specify via the dialog box. It is not. I still
get 72 dpi.
Why does the resolution change from one print() call to another? Why isn't
the resolution specified via the print dialog box being used?
I don't understand this part of your answer:
You can work at any resolution up to whatever is device resolution by simply
applying a suitable scaling transform to the graphics obtained from
PrinterJob
and doing your rendering at that higher resolution.
Are you saying that if device resolution is 600 dpi, I can work at 300 dpi?
Thanks.

I don't understand the comment about controlling which pages are printed.
You - the app - are the originator of the printing so have complete control.
PrinterJob will print at printer device resolution.
Discovering device resolution is just a matter of looking at the scaling
component in the transform of the printer graphics and multiplying by
the user default of 72dpi. NB: recalculate this on every call as there's
no guarantee that it will be the same across all calls on your print()
method.
If a printer offers 300 & 600 dpi resolution there's no way to select
between these two at the device level. That's in late 2001.
But if your concern is that 72dpi is too low you can be assured that the
device resolution being used is higher. And user space is not limited to
72dpi.
You can work at any resolution up to whatever is device resolution by simply
applying a suitable scaling transform to the graphics obtained from
PrinterJob
and doing your rendering at that higher resolution.
