Overview of Spooler FASTP Network Print
Processes

Spooler Environment

The Spooler subsystem is a set of utilities that form an interface between you (and
your application programs) and the print devices of an HP NonStop system. Instead of
directing application output directly to a printer, the Spooler allows you to store the
output as jobs in a disk file, and then peruse or queue the output to be sent to a
designated printer when it becomes available for printing.
Because everything associated with the Spooler supervisor process is part of the
Spooler subsystem, including print processes and devices, configuration of a FASTP
network print process requires configuration of the FASTP network print process as a
print process within the Spooler subsystem. For complete instructions about how to
configure a FASTP network print process as a print process to the Spooler subsystem,
see Configuring a FASTP Network Print Process in the Spooler Subsystem
page 2-5.
For a detailed description of the Spooler subsystem including detailed descriptions of
the Spooler components, how to use the Spooler and the complete command syntax
for the user interfaces, see either the Guardian User's Guide (for G-series systems) or
the Guardian System Operations Guide (for D-series systems), and the Spooler
Utilities Reference Manual.

IOP Environment

The IOP environment on an HP NonStop system typically consists of:

A specific type or adapter (G-series systems) or controller (D-series systems)

An input/output process (IOP)
Note that the IOP might have more than one protocol-specific interface. Depending on
the protocol being used, additional, protocol-specific software might also be required.
The IOP environment used by the FASTP network print processes varies based on the
version of the FASTP network print process in use and whether you are using a D-
series or G-series system. Depending on the IOP being used by your FASTP network
print process, some knowledge of IOP parameters might be required to configure the
FASTP network print process product. For more information about the IOP subsystems
used by the FASTP network print processes, refer to the product-specific FASTP
network print process subsections of this manual.

Control Operations and Job Information

In addition to the Spooler subsystem and FASTCNFG configuration parameters
discussed above, the FASTP network print processes also allow you to alter a printer's
operation by embedding printer-control operations (CONTROL, CONTROLBUF, and
SETMODE) within a Spooler FONT job and by using Spooler job and batch job
subcommands. This information can augment or replace some of that present in the
configuration files. All job-supplied information only affects the current job.
