A DESCRIPTION OF THE PROBLEM :
When I use the ServiceUI.printDialog command on Linux, the only media size option I am seeing (for any printer on our network) is the system default, "Letter". When the same printers are accessed from other, non-Java applications on my computer, I can pick from a variety of media sizes. This issue is also not present on Windows.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached source code and view the media size options for various printers.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect to be able to select common media sizes that are not my system default (for example, A4).
ACTUAL -
Only the default media size ("Letter" on my system) appears.

REPRODUCIBILITY :
This bug can be reproduced always.
