I'm trying to set up a program that will store a user's default printer
properties including which printer to print to (printers are networked).

I get the impression from the JDK documentation and the Java in a
Nutshell books that the Properties object you pass to the getPrintJob
method (of the Toolkit class) is supposed to be "persistent".  Unless
I'm missing something, Java passes parameters by value so I won't get
the Properties object back and I haven't found a method that will get me
the properties from the PrintJob object.  The only persistency I see is
while the program is running and after the user has selected the printer
information once during that session.  

The questions:

Is there any way to find out the properties selected for a PrintJob
object?  Do PrintJob's have a standard set of properties?

If not, is there any way other than serializing the PrintJob object to
maintain that information beyond the current program execution?

Appreciate any and all assistance...
