Print jobs Backwards After SP3 Installed

Today, I came across a client that had some print jobs that were printing out backwards. Never having seen this before, I had to make sure she was telling the truth so I printed a test page from her HP Officejet printer at her desk. Sure enough, the test page printed out backwards. I had no idea why this happened. The only thing that was different in the past few days was that we (meaning the IT dept) did a mass install through WSUS of Windows XP SP3. Apparently, SP3 was the culprit although I am not sure why but here is what happened:

On the print preferences tab of the print queue, there was an option called "mirror image". Somehow, it much have been turned on which causes print jobs to come out backwards. I turned the feature off and printed another test page with no issues. This did not seem to affect network printers, just her local desktop printer.

To give proper credit, I found the solution here: Microsoft Technet

Apparently, this may only be happening if its an HP Officejet printer. Has this happened to you? Do you know why SP3 may have caused this change? Let me know.
