Starting and Stopping the LP Print Service
The LP print service is started by the lpsched daemon and is shut down
by the lpshut command.
Starting the LP Print Service
The lpsched daemon starts or restarts the LP print service. Printers that
are restarted with a lpsched command from the command line, reprint,
in their entirety, the print requests stopped by the lpshut command.
The following is an example of starting the lpsched daemon from the
command line:
# svcadm enable application/print/server
Stopping the LP Print Service
When the command to disable the print service is invoked, any printers
that are currently printing, stop printing.
The lp print service can be disabled. This method should be used to stop
the print server service.
# svcadm disable print/server
# svcs -a | grep print
disabled 19:12:16 svc:/application/print/server:default
online 16:59:49 svc:/application/print/cleanup:default

Specifying a Destination Printer
12-34 Intermediate System Administration for the Solaris™ 10 Operating System
Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1
Specifying a Destination Printer
In the Solaris OS, users submit print requests by using the lp command or
the lpr command.
Note – The Solaris OS LP print service accepts both the SVID

/usr/bin/lp command and the BSD /usr/ucb/lpr command to submit
print requests.
Using the lp Command
The lp command is located in the /usr/bin directory. The lp command
submits a print job to the default printer or to another printer by
specifying the printer name. Perform one of the following commands:
$ /usr/bin/lp
filename
$ /usr/bin/lp -d
printername filename
Using the lpr Command
The lpr command is located in the /usr/ucb directory. The lpr
command functions in the same manner as the lp command. It submits a
print job to the default printer or to another printer.
$ /usr/ucb/lpr
filename
$ /usr/ucb/lpr -P
printername filename
The preceding examples of the print commands demonstrate the atomic
style. You can also use the Portable Open Systems Interface (POSIX) style
to specify a destination printer.
To submit a print request that uses the POSIX style, include the print
command and an option, followed by the printer server name, a colon,
and the printer name as configured on the print server.
The full command-line entry is as follows:
$ /usr/bin/lp -d
hostname:printername filename
$ /usr/ucb/lpr -P
hostname:printername filename

Using the LP Print Service
The LP print service is a set of software commands, utilities, and filters
that allow users to print files and the root user to set up and manage the
print operations.
Table 12-5 lists some of the more commonly used print service
administration commands.
Note – You must be the root user to use these commands.
Accepting Print Jobs
As the root user, you use the accept command on the print server to
permit print requests to be queued on the specified printers.
Using the accept Command
You use the accept command to allow queuing of print requests for the
named destinations. A destination specifies the name of a printer or
printer class.
The format for the command is:
# /usr/sbin/accept
destination(s)
Table 12-5 LP Print Service Administration Commands
Command Name Description
accept Permits print requests to be queued for the
specific printers
reject Prevents print requests from being queued
for the specific printers
enable Activates the specified printers
disable Deactivates the specified printers
lpmove Moves print requests from one printer
destination to another
Using the LP Print Service

12-36 Intermediate System Administration for the Solaris™ 10 Operating System
Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1
In the following example, the root user has enabled the queuing of print
requests on printerD.
# accept printerD
destination "printerD" now accepting requests
Rejecting Print Jobs
As the root user, you use the reject command on the print server to
prevent print requests from queuing on the specified printers.
Using the reject Command
You use the reject command to prevent print requests from queuing and
stop users from submitting requests to the printer queues.
The format for the command is:
# /usr/sbin/reject
-r “reason" destination(s)
The following example shows how to use the option -r “
reason”
to
enter an explanation for the rejection of print requests for a printer. A user
can see that text by issuing the lpstat -a or lpstat -t command.
# reject -r "Replacing Toner Cartridge" printerD
destination “printerD” will no longer accept requests
Enabling Printers
On the print server, as the root user, you can use the enable command to
activate the specified printers.
Using the enable Command
The enable command activates the printers, which enables the printing of
requests submitted to the print queues.
The format for the command is:
# /usr/bin/enable

destination(s)
The following example shows how to enable printerD.
# enable printerD
printer “printerD” now enabled

Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1
Disabling Printers
On the print server, as the root user, you can use the disable command
to deactivate the specified printers.
Using the disable Command
The disable command deactivates printers, which disables them from
printing print requests waiting in the print queues.
By default, any requests currently printing on the printer when the
disable command is issued are reprinted in their entirety when the
printer is enabled again.
The format for the command is:
# /usr/bin/disable -c | -W -r
“reason” destination
Table 12-6 shows the options for the disable command:.
The following example shows how to use the disable command with
options.
# disable -W -r “Printer down for maintenance” printerD
printer “printerD” now disabled
Table 12-6 Options for the disable Command
Option Definition
-c Cancels the current job and disables the
printer. The current job is not printed later.
-W Waits until the current job is finished before
disabling the printer.

-r Assigns a reason for the disabling of the
printer.

Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1
Moving Print Jobs
You use the lpmove command to move one or all print requests from one
printer destination to another printer destination.
Using the lpmove Command
The format for the lpmove command is:
# /usr/sbin/lpmove
source_destination target_destination
To move one or all print requests by using the lpmove command,
complete the following steps.
1. Become the root user on the print server.
2. Use the reject command to prevent any further print requests from
being sent to the print queue. This step notifies users that the printer
is not accepting requests.
# reject -r “PrinterC is down for repairs” printerC
destination “printerC” will no longer accept requests
3. Use the lpstat command to display the print queue to see how
many print requests are to be moved. This step is needed to identify
print request identification numbers (IDs) only if selected print
requests are going to be moved to another printer.
# lpstat -o
printerC-29 sys41!user1 61426 Jan 07 12:30
printerC-30 sys41!user1 9560 Jan 07 12:30
printerC-31 sys42!user2 845 Jan 07 12:30
printerC-32 sys42!user2 845 Jan 07 12:30
printerC-33 sys42!user2 845 Jan 07 12:30

4. Use the lpstat command to verify that the destination printer is
accepting print requests.
# lpstat -a printerA
printer printerA accepting requests since Tue Jan 1
Using the LP Print Service

5. Move the print requests.
a. For example, to move all print requests from printerC over to
printerA, perform the following command:
# lpmove printerC printerA
move in progress
total of 5 requests moved from printerC to printerA
b. For example, to move one or more individual print requests
from printerC to printerA, perform the following command:
# lpmove printerC-32 printerC-33 printerA
total of 2 requests moved to printerA
6. If all print requests were moved from printerC, in step 5a,
printerC has a reject automatically applied to it. When
printerC is available again, use the accept command to allow print
jobs to queue to printerC.
# accept printerC
destination “printerC” now accepting requests

Viewing System Processes
A process is any program that is running on the system. All processes are
assigned a unique process identification (PID) number, which is used by
the kernel to track and manage the process. The PID numbers are used
by the root and regular users to identify and control their processes.
Using the CDE Process Manager
The Solaris OS Common Desktop Environment (CDE) provides a Process
Manager to monitor and control processes that are running on the local
system.
To start the Process Manager, click the Find Process control on the Tools
subpanel of the Front Panel. Figure 13-2 shows the Tools menu.
