OVERVIEW This white paper describes the advantages of Microsoft® driver isolation mode, how it works, which systems it supports, and how to use it with the HP Universal Print Driver (UPD). Background Microsoft® Windows Server versions 2000, 2003, and 2008, along with client versions Windows XP® and Windows Vista®, utilized user-mode version 3 print drivers that operate in the print spooler process spoolsv.exe. If any driver utilizing spoolsv.

USING THE HP UPD IN DRIVER ISOLATION MODE Does the HP UPD support driver isolation mode? The driver in isolation mode is supported for the HP Universal Print Driver 5.0 and higher on Windows 7 and Server 2008 R2. This is true for all HP UPD PDLs (PS/PCL5/PCL6), for x32 and x64 bit, and regardless of supported install method.

Is HP UPD performance impacted in driver isolation mode? Like other drivers on the system, the HP UPD competes for shared resources on the server. System resources are required for each driver(s) placed in isolation mode and the Windows system manages the resource. For each driver defined to run in full isolation mode, a unique instance of PrintIsolationHost.exe must launch, or drivers in shared isolation can share an instance of PrintIsolationHost.exe.

How can I use an HP UPD *.inf file to define isolation mode as the HP UPD installation default (for HP UPD 5x versions prior to 5.1.1)? Before proceeding with the HP UPD installation, add “DriverIsolation=2” string to a UPD *.inf file (see the sample section of an UPD *.inf file below). This change can be made to any of the available *.inf files in the driver package, and changing only one *.inf file is required.
