DESCRIPTION
- lpsched
Schedules requests taken by
lp
for printing on printers.
lpsched
is typically invoked in
/sbin/rc.
This creates a process which runs in the background until
lpshut
is executed.
The activity of the process is recorded in
/var/adm/lp/log.
lpsched
recognizes the following options:
- -v
Write a verbose record of the
lpsched
process on
/var/adm/lp/log.
- -a
Write
lpana
logging data on
/var/adm/lp/lpana.log.
- lpshut
Shuts down the printer scheduler.
All printers that are printing at the time
lpshut
is invoked stop printing.
Requests that were printing at the time the scheduler was shut down
are reprinted in their entirety after
lpsched
is started again.
All LP commands perform their functions even when
lpsched
is not running.
- lpmove
Moves requests that were queued by
lp
between LP destinations.
The first form of the command moves the named
requests
to the LP destination,
dest.
requests
are request IDs as returned by
lp.
The requests that are currently printing will not be moved.
The second form of the command moves all requests
for destination
dest1,
including requests that are currently printing,
to destination
dest2.
As a side effect,
dest1
rejects all subsequent requests.
Note that
lpmove
never checks the acceptance status
(see
accept(1M))
for the new destination when moving requests.
- lpfence
Defines the minimum required
priority
for the spooled file to be printed.
fence
must be in between 0 (lowest fence) and 7 (highest fence).
Each printer has its own fence,
which is initialized to 0 when it is configured by the
lpadmin
command.
EXTERNAL INFLUENCES
Environment Variables
LC_TIME
determines the format and contents of date and time strings.
LANG
determines the language in which messages are displayed.
If
LC_TIME
is not specified in the environment or is set to
the empty string, the value of
LANG
is used as a default for each
unspecified or empty variable.
If
LANG
is not specified or is
set to the empty string, a default of "C" (see
lang(5))
is used instead of
LANG.
If any internationalization variable contains an invalid setting,
the commands
behave as if all internationalization variables are set to "C".
See
environ(5).
EXAMPLES
lpmove laserjet1-1 classlaserjet-30 laserjet3
Move requests
laserjet1-1
and
classlaserjet-30
from destination queues
laserjet1
and
classlaserjet
to the destination queue
laserjet3
if the requests are not currently printing.
lpmove laserjet1 laserjet2
Move all requests from the destination queue
laserjet1
to the destination queue
laserjet2.
This will also cause
laserjet1
to reject all subsequent print requests to it.
All currently printing
requests from
laserjet1
will be reprinted on
laserjet2.
lpfence laserjet1 5
Suppose
laserjet1
is a member of classes
classlaserjet1
and
classlaserjet2.
Running this command
will cause only print requests of priority 5 and above from
queues
classlaserjet1,
classlaserjet2,
and
laserjet1
to be printed on printer
laserjet1.
Print requests of priority 4 and below will not be
picked by the scheduler for printing on
laserjet1.
WARNINGS
lpsched,
lpshut,
lpmove,
and
lpfence
perform their operation on the local system only.
