What Are Objects and Attributes?

With its objected-oriented model, an HPDPS object represents a

physical or logical entity in the print environment. For example, a

speciﬁc printer device is represented as a physical printer object. Speciﬁc

printer capabilities, on the other hand, are represented as a logical

printer object.

All HPDPS objects such as physical printers, logical printers, spoolers,

supervisers, queues, documents, and jobs have collections of attributes,

or deﬁned characteristics, assigned to them. For example, one of the

attributes of a physical printer is called printer-model,reﬂecting the

make and model of the printer device represented by the physical printer

object. An attribute has a speciﬁc value assigned to it; for example, the

attribute printer-model might have the value LaserJet4Si.

Some of the attributes are given default values when you create the

object. For others, the values you associate with attributes as you

conﬁgure your HPDPS print environment affect how HPDPS processes

the jobs submitted by your users. Additionally, users can specify values

for attributes of jobs and documents when they submit jobs.
