Driver updates

Print drivers

The latest print drivers for many HP network printers are supplied on the Service Release DVD. If selected

as pa rt of the service release installation process, updated print drivers are copied to the print drivers

folder C:\hpnas\PRINTERS on the storage server. Print drivers are also 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 mod e (also calle d version 3 drivers) or kernel mode (also called

version 2 driv

ers). Native drivers on Windows 2000 and later run in user mode. Windows Server 2003

and Windows Storage Server 2003 can run kernel-mode drivers, although this is not recommended for

stability reasons.

Kernel-mode driver installation blocked by default

In Windows Server 2003 and Windows Storage Server 2003, installation of kernel-mode drivers

is blocked by default.

To allow kernal-mode drivers to be installed, perform the following steps:

1. Open Group Policy, click Start > Run,thentypegpedit.msc,andpressEnter.

2. Under Local Computer Policy,double-clickComputer Conﬁguration.

3. Right-click Disallow installation of printers using kernel-mode drivers, and then click Properti es.

4. On the Setting tab, click either Not Conﬁgured or Disabled, and then click OK.

Printer server scalability and sizing

A Microsoft technical paper overviews several key factors that in ﬂuence the capacity of a given print

server c on ﬁgura tion. While this p aper cannot provide a predictive formula to d etermine the printing

throughput of a given conﬁguration, it does describe several reference systems and their capacity. This

paper also presents the information necessary to help the system a dministrator or capacity planner

estimate, and later m onitor, their server workload. The current version of this paper is maintained at

ttp://www.microsoft.com/printserver.

Backup

It is re commended that yo u back up the p rint server conﬁguration whenever a new printer is added to the

network a nd the print server conﬁguration is modiﬁed. For details on implementing the backup solution,

see the Medium Business Guide for Backup and Recovery. The guide c an be viewed or downloaded

from Microsoft at h

ttp://www.microsoft.com/ technet/itsolutions/smbiz/mits/br/mit_br.mspx.
