NAME

lpsched, lpfence, lpmove, lpshut - start and stop LP request scheduler, move requests, set minimum print-

ing priority

SYNOPSIS

/usr/sbin/lpsched

[ -v ][-a ]

/usr/sbin/lpshut

/usr/sbin/lpmove

requests dest

/usr/sbin/lpmove

dest1 dest2

/usr/sbin/lpfence

printer fence

DESCRIPTION

lpsched Schedules requests taken by lp(1) for printing on line printers. lpsched(1M) 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(1M) logging data on /var/adm/lp/lpana.log

lpshut Shuts down the line printer scheduler. All printers that are printing at the time lpshut is

invoked stop printing. Requests that were printing at the time a printer 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(1) between LP destinations. This command can be

used only when lpsched is not running.

The ﬁrst form of the command moves the named requests to the LP destination, dest. requests

are request ids as returned by lp(1). The second form moves all requests for destination dest1

to destination dest2. As a side effect, lp(1) rejects requests for dest1.

Note that

lpmove never checks the acceptance status (see accept(1M)) for the new destina-

tion 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 initial-

ized to 0 when it is conﬁgured by the lpadmin(1M) command.

lpfence is used only when

lpsched is not running.

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, lpsched, lpmove, and lpshut behave as if all internationalization variables are set to "C". See

environ(5).

WARNINGS

Moving requests associated with remote printers can cause unpredictable results.

lpsched, lpshut, lpmove, and lpfence perform their operation on the local system only.
