Introducing HP Distributed Print Service
The Two HPDPS Environments
The Two HPDPS Environments
HPDPS can operate within either of two environments. In the first, it
optionally uses Distributed Computing Environment (DCE) services to
interact with a heterogeneous mix of hardware and software products as
if they were a single print environment. When HPDPS interacts with
DCE, the environment is called the DCE Extended Environment.
This environment requires separately purchased DCE Security software.
In the second environment, called the Basic Environment, when
HPDPS is not part of DCE, it uses only the limited DCE services bundled
with the HP-UX operating system.
The DCE Extended Environment
In the DCE Extended Environment, HPDPS objects (such as physical
printers and spoolers) created by any member of a DCE cell are instantly
available to the entire cell. For example, if a new physical printer is
created within a DCE Extended Environment server, the name of the
new physical printer is visible to every client in the DCE cell, and each
client can immediately issue HPDPS operations for that physical printer.
This is possible because the entire cell shares the same namespace called
the DCE Cell Directory Service. This allows for single-point
administration as a result of the distributed namespace. See Chapter 8 ,
“Managing DCE Security for HPDPS,” for more information on the DCE
Extended Environment.
The Basic Environment
In the Basic Environment, only a local namespace is visible to HPDPS.
Objects created on one host are not instantly accessible to the other hosts
in the network. You can create special logical printers, called HPDPS
Gateway Printers, to access printers on another host. See “HPDPS
Gateway Printer Considerations” in Chapter 3 for more information.
Administration is possible only for those resources that reside within the
boundaries of the Basic Environment namespace. Accordingly,
single-point administration across hosts is not a feature of Basic
Environment.
