Objective 1—Understand How CUPS Works

3

• To understand how CUPS works, you need to understand the following:• Steps of the Printing Process• Print Queues• Log Files


Steps of the Printing Process

• The printing process involves the following steps:– A print job is submitted by a user or by a program– The file destined for the printer is stored in a print

queue• Creates two files per print job in the directory

/var/spool/cups/

– The cupsd printer daemon acts as the print spooler– The conversion of print data is done (See Figure 12-1)– Once the print job has been transferred to the printer,

the print spooler deletes the job from the queue and starts processing the next job

4


Steps of the Printing Process (continued)

Figure 12-1 Filtering process


Print Queues

• Printer devices are addressed using print queues– Print jobs are sent to a print queue associated with the

device

• On a print server, each print queue is registered with its name in the /etc/cups/printers.conf file– Several print queues can be defined for one printer

• Each existing queue has its own configuration file– Stored on the print server in the /etc/cups/ppd/ directory

• On the client side, the names of queues are registered in the /etc/printcap file

6


Log Files

• The access_log File– Lists each HTTP resource that is accessed by a Web

browser or CUPS/IPP client

• The page_log File– Lists each page that is sent to a printer

7


Log Files (continued)

• The error_log File– Lists messages from the scheduler (such as errors

and warnings)

8


Configuration File

• The configuration file for CUPS is /etc/cups/cupsd.conf– Format is similar to that of the configuration file for the

Apache Web server

• Various options are used to configure the server itself– As well as to configure filtering, networking, browsing,

and access

9


Objective 2—Configure Printers and Queues

• YaST provides printer installation and configuration functionality

• To configure a printer, you need to know the following:– When to Configure a Printer– Required Printing Software– Add a Printer– Manage Print Queues with the GNOME Printers

Dialog

10


When to Configure a Printer

• You can configure your printer at the following times:– During installation– After installation

11

Add a Printer

• Add a printer with YaST– The Printer Configuration dialog used to configure your

printer is the same during and after installation– See Figures 12-2 and 12-3– Available printer types

• New Queue for Existing Printer– See Figure 12-4

protocols– Print via CUPS Network Server

• See Figure 12-8

• Types of connections for the CUPS server

– CUPS Client Only (see Figure 12-9)

– CUPS Using Broadcasting (see Figure 12-11)

– Remote IPP Queue (see Figure 12-13)

Manage Print Queues with the GNOME Printers Dialog

• In the Printers dialog (Computer > Control Center > Printers)– Select a printer icon to open the Printing dialog for a

printer– See Figure 12-23

• Use the menus, or the context menu available when right-clicking on a print job, to start or to stop a job, or to remove a job from the queue

34

• In this exercise, you add a local printer to a remote queue


Exercise 12-1: Change Your Printer Configuration

35


Objective 3—Understand Novell iPrint

• Novell iPrint extends print services securely across multiple networks and operating systems

• To use Novell iPrint effectively on SUSE Linux Enterprise Desktop 10, you need to understand the following:– Describe the Purpose and Architecture of Novell iPrint– Configure Novell iPrint– Install the Novell iPrint client

36


Describe the Purpose and Architecture of Novell iPrint

• What Novell iPrint is– Novell iPrint lets mobile employees, business

partners, and customers access printers from a variety of remote locations using existing Internet connections

– Novell iPrint uses the Internet Printing Protocol (IPP), which has the following benefits:

• Uses the IP protocol

• Provides broad vendor support

• Works over local networks and the Internet

• Provides for print data encryption (SSL, TLS)

• Provides a standard print protocol for all platforms

37


Describe the Purpose and Architecture of Novell iPrint (continued)

• Browser-enabled printer installation interface

• Customizable user interface

• Secure information transfer

– For secure printing needs, Novell iPrint integrates with Novell eDirectory

39



• Novell iPrint components on Linux– Main components:

• The Print Manager, the Driver Store, and the Novell iPrint client

– Other supporting components:• Apache Web Server, Novell iManager, and eDirectory

– Print Manager• Provides a platform for Printer Agents to reside on the

server

• Printer Agents are representations of actual printers

– To deliver the Novell iPrint client, and possibly printers, to your client workstations

62


Exercise 12-2: Printing with the Novell iPrint Client

• In this exercise, you install and use the Novell iPrint client

63


Summary

• SUSE Linux uses the CUPS printing system by default

• CUPS uses IPP, but can support the socket, LPD, IPX, and SMB printing protocols

• You can configure a CUPS printers during installation, or after installation using YaST, the GNOME Printers dialog, or by editing the appropriate configuration files in the /etc/cups directory and restarting the CUPS daemon

64


Summary (continued)

• CUPS print jobs are sent to a queue directory (/var/spool/cups) before being sent to the printer itself

• The CUPS daemon writes logging information to the /var/log/cups/error_log, /var/log/cups/access_log, and /var/log/cups/page_log files

• Novell iPrint can be used to install, access, and manage IPP printers remotely using a Web browser

• Before adding printers to Novell iPrint, you must first create a Driver Store as well as configure a Print Manager with Printer Agents
