Introduction to the Spooler
The Compaq NonStop™ Kernel spooler is a set of programs that acts as an interface
between your application programs and the printers on your system.
When you run a NonStop™ Kernel program and print something:
1. You send the output to the spooler.
2. The spooler receives the output, stores it as a spooler job in a print queue on disk,
and monitors the status of the printer.
3. The spooler keeps the spooler job in the print queue until the designated printer
becomes available.
4. The spooler sends the output to the printer to be printed.
The NonStop™ Kernel spooler:
•
Keeps operating even if a processor or disk fails.
•
Lets you change the destination of a job after it enters the spooler. For example, you
can send a job to a holding location on the spooler print queue and then select a
printer while the job is on the queue.
•
Lets you monitor and control the status of your jobs, examine a spooler job before
you print or delete it, and change the printer for your output. No programming is
necessary; send your output to the spooler simply by specifying a spooler location as
your OUT file.
•
Lets an operator monitor and control all spooler components.
You access the spooler by running either:
•
Spoolcom (the spooler management utility), the primary tool that system operators
and managers use for interactive control of the spooler
•
Peruse, which lets all users view and control their own print jobs
