Revert a change to printer orientation

Reverting change: Ia6bc9ae14d79a646e61bfc97652f9f5af90738b3
The previous change does not set the printer correctly. It looks
based on the tests that the correct printer is set, but in reality
the default printer is used (even though printerName() is returning
the printer set).

Updated taskQTBUG4497_reusePrinterOnDifferentFiles() test case
so that it generates PDF instead of PS. Testing the binary output
can't be guaranteed to work in this case.
