A computer that is running Windows 7, Windows Vista, Windows Server 2008 or Windows Server 2008 R2 continues to use the original printer driver after you update or replace the printer driver

Applies to: Windows 7Windows VistaWindows Server 2008 More

Symptoms


You install a printer by using PrintUI.dll together with the device information file (INF) on a computer that is running one of the following operating systems:
  • Windows Vista
  • Windows Server 2008
  • Windows 7
  • Windows Server 2008 R2
In the INF file, you update or replace an existing printer driver. However, the operating system continues to use the original printer driver.

Cause


This issue occurs because PrintUI.dll does not check the minor revision number of a printer driver when you update or install the driver. Therefore, the latest driver does not replace the original driver if both drivers have the same major revision number.

Resolution

Workaround


After you install the hotfix, PrintUI.dll has the additional supported switch /R. The /R switch forces the printui utility to replace the existing driver with the selected driver. For example, you can run the following command to install a printer that is named MyPrinter by using the driver that the end-user selects:

rundll32 printui.dll PrintUIEntry /if /b "MyPrinter" /r "lpt1:" /m "" /w /R

Note This switch is not documented in Help in Windows 7, in Windows Vista, in Windows Server 2008 or in Windows Server 2008 R2.

Status


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
