To use the full capabilities of HPDPS requires using the HP9000
Distributed Computing Environment (DCE), a separately purchased
product. If your host system is configured as a DCE cell, you can
implement the HPDPS Extended Environment, which features a
multiplatform client/server infrastructure, single-point administration,
client authentication, and object authorization.
HPDPS can also be configured without DCE. Using the HPDPS Basic
Environment, HPDPS still provides more functionality and scalability
than the LP spooler, but some configuration must be managed locally,
instead of from a single point of administration.
Simply stated, HPDPS consists of three kinds of printer management
objects:
client Functionality, consisting of daemon and commands,
which allows users to issue print requests and
administrators to manage the print environment.
spooler Process that controls logical printers and queues.
supervisor Process that manages and controls physical printers.
Depending on implementation, these objects may be configured on a
single system or distributed on several computer systems.
HPDPS also uses a Gateway Printer, a logical printer similar to a
“remote printer” provided by the LP spooler. A Gateway Printer allows
you to direct a print request between the Basic Environment and the
DCE Extended Environment and between hosts within the Basic
Environment.
Why use HPDPS?
Using HPDPS, the administrator can manage the following kinds of
settings from a single location:
• Distributed print environments, in which printers are located in
physically diverse locations on a LAN.
• Large-scale environments, in which there is a high volume of
printing and many printers to manage.
HPDPS provides the following features:
• Manage your entire print system from any HPDPS client in the
network. If you are using HPDPS from a DCE environment, you can
configure and monitor your network printing system from any
