EXTRA RELEVANT SYSTEM CONFIGURATION :
requires 2 printers.

A DESCRIPTION OF THE PROBLEM :
printJob ignores the printer selected in cross platform print dialog

my speculation is, all attributes passed to printJob.print are ignored, but that's just a guess.

REGRESSION. Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the program, select the non-default printer.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
print to the selected printer
ACTUAL -
prints to the default printer

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
use the native dialog, not the cross platform dialog.
