> QPrinterInfo provides more details on the print device hardware
> QPrinter uses QPageSize and QPageLayout to improve page layout handling

> Mac can now have each painted page with a different orientation, and can set

> Mac and Windows now support setting Document Creator and Duplex Mode
> Mac and Linux now support using Windows Page ID (DMPAPER values)
> Linux now requires CUPS 1.4 (RHEL 5 no longer supported)
