Controlling Printer Activity
You may use the SPOOLER command to start, suspend, resume and stop
spooler processes, and release spoolfiles from a spooler process. The
SPOOLER command may be entered only at the console unless enabled to
other users with the ALLOW or ASSOCIATE commands.
To start the spooler
Entering the START parameter with an ldev parameter opens the spool queue
for the specified device and starts a spooler process for only that
device. The use of SPOOLER;DEV=nn;START allows spoolfiles targeted for
that device and any device class name that contains that device to print.
To start a spooler process for each device in devclass LP, enter:
SPOOLER DEV=LP;START
Or, because DEV= is optional, enter:
SPOOLER LP;START
To suspend spooling
The SUSPEND parameter within the SPOOLER command temporarily suspends the
spooler process. The spooled device remains spooled and the queue
maintains its current status (open or shut). To suspend printing, enter:
SPOOLER 6;SUSPEND
To suspend spooling but let current spoolfile finish.
When a spooler is suspended, spoolfiles may continue to be created but
the spooler process does not continue to print files. To suspend
spooling but allow a current spoolfile to finish printing, enter:
SPOOLER 6;SUSPEND;FINISH
To reprint a specified number of pages.
The - option of the OFFSET parameter indicates that the offset is
backward rather than forward. In the example below, printing would
resume three pages back from the last page printed, unless the offset is
further adjusted with the ;RESUME or ;RELEASE options. To reprint three
pages, enter:
SPOOLER 6;SUSPEND;OFFSET=-3
To move ahead a certain number of pages.
The + option of the OFFSET parameter indicates that the offset is
forward. In the example below, printing would resume five pages forward,
unless the offset is further adjusted with the ;RESUME or ;RELEASE
options. To move ahead from the last page printed, enter:
SPOOLER 6;SUSPEND;OFFSET=+5
To begin printing on a specified page.
The absence of a + or - indicates an absolute offset from the beginning
of the spoolfile.
To begin printing on a specified page, enter:
SPOOLER 6;SUSPEND;OFFSET=7
If ;OFFSET is not specified, printing resumes at the page where it was
stopped. This is also the default.
To print a spoolfile at its beginning.
It is important to understand that pages are defined only for control of
intelligent peripherals (CIPER) protocol devices and HP 2680 and HP 2688
page printers. For these devices, a page is one physical sheet. Pages
are not defined for other devices, and the results of using the ;OFFSET
parameter are unpredictable for them. To print a spoolfile from the
beginning, enter:
SPOOLER 6;SUSPEND;OFFSET=1
To suspend spooling immediately.
The combination of the NOW, KEEP, and zero OFFSET parameters (all
defaults) is a unique situation. When the spooler receives this form of
the SUSPEND option, it suspends after processing the current record. To
suspend printing immediately, enter:
SPOOLER 6;SUSPEND;NOW
Because ;NOW is the default, it may be omitted.
To resume spooling
Use the ;RESUME option of the SPOOLER command to restart the spooler
process. If the spooler process retained a spoolfile while it was
suspended, you can specify where to restart the printing. To resume
printing, enter:
SPOOLER 6;RESUME
To resume printing at the beginning of the spoolfile.
Use the OFFSET parameter of the SPOOLER command to resume printing at the
beginning of a spoolfile:
SPOOLER 6;RESUME;OFFSET=1
To resume printing on a particular page.
If you know the page number of the spoolfile that you want to start on
(for example, page 7), enter:
SPOOLER 6;RESUME;OFFSET=7
To resume and reprint a certain number of pages.
Use the - option of the OFFSET parameter to back up a certain number of
pages:
SPOOLER 6;RESUME;OFFSET=-4
To resume and move ahead a certain number of pages.
Use the + option of the OFFSET parameter to move ahead to certain pages:
SPOOLER 6;RESUME;OFFSET=+4
The plus sign means advance four pages from where it is now. Without the
plus sign, it means page number 4.
To stop a spooler process
Use the STOP option of the SPOOLER command to stop a spooler process.
For example:
SPOOLER 6;STOP
This command also closes the spooling queues for logical device 6.
To stop the spooler process but leave spooling queues open.
Use the OPENQ option to stop the spooler and leave the spooling queues
open. For example:
SPOOLER 6;OPENQ;STOP
