If a machine running Windows 7 or Windows Server 2008 R2 has the Windows Aero theme setting applied, when changing the print settings in the print dialog, the background bitmap in the Current Setting view of the driver UI might be black. Queues of the same driver inherit each others' settings. Repeated installation and removal of the driver could result in a large number of registry entries building up and affecting performance. Registry entries remain on the system after a driver uninstallation. Within a Microsoft Word or Excel document, if a Word file that has a custom paper size that is not supported by the driver is inserted as an object, the layout in the object does not render correctly. PCL XL error, job cancellation, or hang-up when printing dotted lines in jobs from applications such as Microsoft Project 2010. Print settings configured within an application are overridden by the driver. The PCL XL error 'FontNameAlreadyExists - XXX' is produced if printing a job containing non-ASCII characters (multi-byte) and both of the following conditions are met: The OS is of a language that only uses single byte characters (such as English) & The Windows System Locale is of a language that uses multi-byte characters (such as Japanese or Chinese). PCL XL error 'UnsupportedCharacterFormat' produced when printing from IE9. Drivers installed via point and print are not completely removed from the system after a driver uninstallation.
