HPDPS Architecture

What Is an HPDPS Logical Printer?

An HPDPS logical printer represents an abstract set of job and printer

capabilities, such as the types of document formats supported and the

types of media supported. Your users submit their jobs to logical printers,

which then verify that there are physical printers capable of handling

the jobs. Once veriﬁed, the logical printer sends the job to an associated

queue.

You can deﬁne a default logical printer for your users, and you can

conﬁgure other logical printers to restrict the access of users to printers.

You might want to restrict access for reasons such as security, job

management, or printer capabilities. “Creating and Conﬁguring Logical

Printers” in Chapter 6 describes the conﬁguration tasks you can perform

for HPDPS logical printers.

What Is an HPDPS Queue?

An HPDPS queue schedules jobs on physical printers.

One or more HPDPS logical printers can send jobs to a single HPDPS

queue, and a queue can have one or more associated physical printers.

See “Creating and Conﬁguring Queues” in Chapter 6 for the

conﬁguration tasks related to HPDPS queues.

What Is an HPDPS Spooler?

The HPDPS spooler is the server that controls the logical printer and

the queue. The spooler does the following:

• Applies speciﬁed defaults to jobs

• Validates that jobs can be printed using the printers on the network

• Schedules jobs from queues to physical printers

What Is an HPDPS Supervisor?

The HPDPS supervisor is the server that manages and controls the

physical printer. The supervisor:

• Receives jobs from the spooler

• Directs jobs to the physical printer

• Reports errors to the spooler and the client
