Print drivers
The latest print drivers for many HP network printers are supplied on the Service Release DVD. If selected
as part of the ser vice release installation process, updated print drivers are copied to the print drivers
folder C:\hpnas\PRINTERS onthestorageserverorFilePrintAppliance. Printdriversarealso
available for download on the HP Support web site for individual network printers.
User-mode vs. kernel-mode drivers
Drivers can be written in either user mode (also called version 3 drivers) or kernel mode (also called
version 2 drivers). In Windows NT 4.0, drivers were moved into kernel mode to improve performance.
However, when a kernel-mode driver fails, it can crash an entire system, whereas the failure of a user-mode
driver causes only the current process to crash. Because of this difference, native drivers on Windows
2000 and later run in user mod e. Windows Server 2003 and Windows Storage Server 2003 can still
run kernel-mode drivers, although this is not recommended for the stability reasons mentioned here.
To check whether a driver you have installed is user mode or kernel mode, do the following:
1. On the storage server desktop, click Start,chooseSett ing s, and then Printer and Faxes.
2. Click File and them click Server Properties.
3. Click the Drivers tab.
4. View the Version column for a specicdriver.
If the version indicates Windows NT 4.0 you have a kernel-mode driver.
If the version is Windows 2000, Windows XP, or Windows Server 2003, you have a
user-mode driver.
Kernel-mode driver installation blocked by default
In Windows Server 2003 a nd Windows Storage Server 2003, installation of kernel-mode drivers
is blocked by default.

2. Under Local Computer P olicy,double-clickCom puter Conguration.
