KB2004234: After upgrading a printer driver on any Microsoft Operating system later than
Windows XP and Server 2003, the old driver files are still being used.
For Microsoft Windows 7 and Microsoft Windows 2008R2, please reference the following Microsoft
printing core components update: http://support.microsoft.com/kb/2647753
Enterprise environments that have a unidrv.dll and/or pscript5.dll version older than the version packaged
in the UPD may experience symptoms defined in the Microsoft articles. Administrators should identify the
unidrv.dll or pscript5.dll version installed in the \windows\system32\spool\drivers\*\3 directory, compare to
the UPD Version History table in this release note, and create appropriate testing and deployment plans
specific to the installation environment.
USB Plug and Play
NOTE: The HP LaserJet USB (DOT4) communication driver must be installed on Windows 8 / 8.1 and
Windows Server 2012 systems prior to connecting the device. This component is available for download
at http://www.hp.com/go/upd.
Starting with UPD 5.6.5, new options in install.exe add the ability to select USB mode for USB Plug and
Play with options to remove all versions of HP Universal Printing Driver from Windows driver store, or to
add the HP Universal Printing Driver to Windows driver store. The feature removes reliance on
Microsoft’s pnputil.exe to stage drivers to the windows driver store and allows control of the ranking
process used by the Microsoft operating system when selecting an HP UPD driver version during plug
and play USB install. The new features do not apply to Windows XP or Server 2003.
NOTE: When using UPD with Smart Install capable devices, the Smart Install feature must be disabled at
the control panel of the device prior to connecting the device to the computer. Please see the device
documentation for instructions on disabling Smart Install.
