HPDPS Terminology

HPDPS Terminology
All jobs are printed on hardware called printers or printer devices.
Within your printing system, there are likely to be many printer devices
with each device having its own capabilities. For example, some printer
devices can print on both sides of the page, some can print PostScript
documents, and so on. HPDPS internally represents each printer device
and its capabilities as a physical printer. Each physical printer within
an HPDPS environment has an associated print queue and logical
printer, defined below.
When you submit a job for printing, you submit it to a logical printer.
HPDPS uses a logical printer to check (validate) the printer
requirements of a job and determine if there is a physical printer capable
of handling the job requirements before the job is accepted. When
HPDPS accepts the job, the logical printer provides some default values
for the job and places the job in a print queue where the job waits until
an appropriate physical printer is available to print the job.
HPDPS manages and prints jobs by using objects such as printers, jobs,
and queues. Each HPDPS object has attributes and associated attribute
values. For example, the attributes of a job define the printer
requirements of the job, and the attributes of a physical printer define
the capabilities of the printer device it represents. Using particular
attribute values, HPDPS can determine which printer device is capable
of printing the job.
The logical printers, queues and physical printers to which you have
access are all managed by a server. The HPDPS environment has two
types of servers: the spooler and the supervisor. The HPDPS spooler is
the server that manages the logical printers. The HPDPS supervisor is
the server that controls the physical printers that print the job.
Each HPDPS command described in this book acts on one or more of
HPDPS objects. These commands enable you to submit, modify and
remove jobs. They also enable you to query the status and attributes of
your jobs and all the other objects in your HPDPS environment.
If HPDPS uses Distributed Computing Environment (DCE) services, the
environment is called a DCE Extended Environment; if DCE services
are not used, then HPDPS operates in a Basic Environment. This has
implications for how your print system is set up. See the HP Distributed
Print Service Administration Guide for more information.
