Planning Your Physical Configuration
Understanding how many basic HPDPS components to install is
important when you are designing your HPDPS environment.
If you need a minimum HPDPS configuration, you will have to install a
client, a spooler, and a supervisor. If you need to increase the size of your
HPDPS printing system, you will want to install additional clients,
spoolers, and supervisors on the systems that will best support your
printing needs. You will want to base the number of servers you install
on the number and location of the printer devices you are supporting and
on the number and size of the jobs those devices handle.
Determining How Many Clients to Install
Each host machine that executes HPDPS commands must have an
HPDPS client installed.
Determining How Many Spoolers to Install
One spooler will typically support many hosts, especially in the DCE
Extended Environment. However, you will need to consider adding more
spoolers if any of the following situations occur:
• The number and size of jobs being spooled exceeds the system
capacity. Chapter 2 , “Installing HP Distributed Print Service,”
provides information to help you with this calculation.
• The user groups you support are competing for printer devices and
they each need dedicated system support. Setting up individual
spoolers for the groups ensures that jobs for each group are handled
independently.
• The user groups you support have very different printing
requirements. For example, one group prints informally and
sporadically based on the needs of individuals, and another group
maintains an intense production printing environment with
consistent, predictable print requirements.
Because under the DCE Extended Environment you can monitor the
entire print environment from your HP-UX system, managing multiple
spoolers requires almost no more effort than managing a single spooler.
