Tested with merlin-beta_refresh b71 on RedHat Linux 6.2J and 6.2J Update.

Printing causes java.awt.print.PrinterIOException as below;

To reporoduce;

1. Compile and run attached test case (PrintTest_C.java)
   % java PrintTest_C
2. Page Setup dialog comes up and press OK
3. Print dialog comes up and press Print.

Then, you can see the problem.

This test case works correctly with merlin-beta_refresh b70.
Therefore, this is regression.
