Driver updates

Print drivers

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

as part of the service release installation process, updated print d rivers are copied to the print drivers

folder C:\hpnas\PRINTERS on the storage ser ver. Print drivers a re 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 mode (also called version 3 drivers) or kernel mode (also called

version 2 driv

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

and Windows Storage Server 2003 c an 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-mod e 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.

Printer server scalability and sizing

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

server conﬁguration. While this paper cannot provide a predictive formula to determine 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 administrator or capacity planner

estimate, and later m onitor, their server workload. The current version of this pap er is m aintained at

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

Backup

It is recommended that you back up the print server c on ﬁguration whenever a new printer is added to the

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

see the M edium Business Gu ide for Backup and Recovery. The guide can be viewed or downloaded

from Micr osoft at h

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

The P rint Migrator utility is recommended as a print-speciﬁc alternative to backing up

print conﬁguration settings on the print server. The Print Migrator utility is located in the

C:\hpnas\Components\PrintMigrator folder on the storage server.
