Starting and Stopping the LP Print Service Configuring and Using Printer Services 12-33 Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1 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 online 19:01:10 svc:/application/print/rfc1179:default offline 19:12:16 svc:/application/print/ipp-listener: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 Configuring and Using Printer Services 12-35 Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1 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 Using the LP Print Service Configuring and Using Printer Services 12-37 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. Using the LP Print Service 12-38 Intermediate System Administration for the Solaris™ 10 Operating System 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 Configuring and Using Printer Services 12-39 Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1 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 Performing the Exercises 12-40 Intermediate System Administration for the Solaris™ 10 Operating System Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1 Performing the Exercises You have the option to complete any one of three versions of a lab. To decide which to choose, consult the following descriptions of the levels: ● Level 1 – This version of the lab provides the least amount of guidance. Each bulleted paragraph provides a task description, but you must determine your own way of accomplishing each task. ● Level 2 – This version of the lab provides more guidance. Although each step describes what you should do, you must determine the commands (and options) to input. ● Level 3 – This version of the lab is the easiest to accomplish because each step provides exactly what you should input to the system. This level also includes the task solutions for all three levels. Exercise: Using the LP Print Service (Level 1) Configuring and Using Printer Services 12-41 Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Sun Services, Revision A.1 Exercise: Using the LP Print Service (Level 1) In this exercise, you use the Solaris OS print manager to set up a print spooler that sends output to a local terminal window, adds access to a remote printer, and uses print management commands. Preparation The host name and IP address of the system that controls the printer you want to access must exist in the /etc/inet/hosts file. Refer to the lecture notes as necessary to perform the tasks listed. Remote Lab Data Center (RLDC) In addition to being able to use local classroom equipment, this lab has also been designed to use equipment located in a remote lab data center. Directions for accessing and using this resource can be found at: http://fn1.brom.suned.com/ Ask your instructor for the particular SSH (Secure Shell) configuration file you should use to access the appropriate remote equipment for this exercise. Tasks Complete the following tasks: ● Open two terminal windows. Record the pseudo-terminal device used by one of them. In the other window, run the Solaris OS print manager, and define a local Lexmark printer that uses the first window’s terminal as its output device. Test the new printer. (Steps 1–7 in the Level 2 lab) ● Use the Solaris OS print manager to gain access to a printer defined on another system. Test the remote printer. (Steps 9–13 in the Level 2 lab) ● Manipulate your Lexmark printer to: ● Disable printer output ● Queue four files for printing Exercise: Using the LP Print Service (Level 1) 12-42 Intermediate System Administration for the Solaris™ 10 Operating System Copyright 2005 Sun Microsystems, Inc.
