Setting Up iPrint on Client
Workstations
When installing SUSE®Linux Enterprise Desktop (SLED), you can choose to install the iPrint
Linux Client. The iPrint Client lets you easily install printers using your Web browser. The
following sections help you understand and use the iPrint client:
•Section 1.1, “Understanding iPrint,” on page 7
•Section 1.2, “Understanding Security,” on page 8
•Section 1.3, “Installing the iPrint Linux Client,” on page 9
•Section 1.4, “Installing Printers,” on page 11
•Section 1.5, “Removing iPrint Printers,” on page 11
•Section 1.6, “Managing Print Jobs from the Client,” on page 12
•Section 1.7, “Using iprntcmd,” on page 12
•Section 1.8, “Uninstalling the iPrint Client,” on page 14
1.1 Understanding iPrint
The iPrint system consists of two pieces: the iPrint Manager that runs on the server and the iPrint
Client that runs on the workstation.
1.1.1 iPrint Manager
The iPrint Manager does the following:
• Spools print jobs from clients
• Sends print jobs to printers
• Maintains printer status information
• Manages the print database
• Maintains the iPrint Printer List page used to install and monitor printers
1.1.2 iPrint Client
The iPrint Client lets Linux workstations install iPrint printers and includes the following
components:
• Browser plug-in: The iPrint Client contains a browser plug-in for Mozilla*-based browsers.
This plug-in lets you install printers into CUPS using your Web browser.
• Console utility: The Linux iPrint client includes the iprntcmd utility that lets you install
printers, print test pages, and upload drivers to a driver store from a console prompt. For more
information, see Section 1.7, “Using iprntcmd,” on page 12.
• CUPS Integrator: The client integrates with the CUPS backend and uses the CUPS local
spooler to send print jobs to the Print Manager.

•CASA:CASA (Common Authentication Services Adapter) is a separate package that you
install with the iPrint client to cache your username and password for secure printers. If you do
not access secure printers, then you do not need CASA.
Figure 1-1 Using iPrint
The following steps are taken when installing a printer and printing to it:
1. Using your Web browser, you access the iPrint Printers List or a custom map, as specified by
your administrator.
2. When you click a printer in the list or on a map, the iPrint plug-in creates the printer and installs
the associated PostScript* Printer Definition (PPD) file in CUPS. After a printer is installed,
you do not need to repeat this process for the same printer.
3. With the iPrint printer installed, you can print from any application as you normally would. The
printer appears as printer in your printer list. The application sends the print job to CUPS for
processing.
4. CUPS gives the print job to the iPrint backend, which sends it to the iPrint Manager. When the
printer is ready, the iPrint Manager sends the job to the printer.
1.2 Understanding Security
The Linux iPrint Client is packaged in two different, specialized installations that control access to
the workstation's print system. The following table explains the differences between the two clients.

Setting Up iPrint on Client Workstations 9
novdocx (ENU) 01 February 2006
The above clients do not affect installation of the iPrint Client, just access to the workstation print
system. To install the iPrint Client you still need root permissions. Also, these clients do not limit
printing capabilities.
IMPORTANT: To install the iPrint Client you need root permissions. To upload drivers from the
system, you need to be defined with lppasswd or know the root password; otherwise, when you
attempt to add drivers from the system, the driver list is blank. To define a user to be part of
lppasswd, you can use the following command:
lppasswd -a linux_user_account -g sys
For more information on the client installed on your SUSE Linux Enterprise Desktop workstation,
consult with your network administrator.
1.2.1 Printing to Secure printers
When installing a secure iPrint printer, you might be prompted twice for your username and
password. First you are prompted to provide your network credentials to verify that you have access
to the printer (it would be no use installing a printer that would not allow you to print). The second
prompt is for CUPS to ensure you have rights to install printers on the client machine. Each time you
perform a print operation with a secure printer, you are prompted for your username and password.
If you installed CASA (Common Authentication Services Adapter), your credentials are cached.
Printing to secure printers is supported only when you are logged in to the desktop. If for any reason
the CUPS iPrint backend cannot deliver the job to a secure printer, the job is requeued on the client
with a hold. You can then see the held job and release it after you log in to the desktop.
1.3 Installing the iPrint Linux Client
The following sections provide information about installing the iPrint Linux Client:
•Section 1.3.1, “Requirement,” on page 10
•Section 1.3.2, “Procedure,” on page 10
Client Filename Workstation Access Description
novell-iprint-xclient-sh-
release_date.i586.rpm
Security high. Limited
access to the print
system.
This client requires workstation users to
be defined with lppasswd to install,
delete, or administer printers on the
workstation. When performing one of
these print operations, the user is
challenged for a password.
novell-iprint-xclient-sl-
release_date.i586.rpm
Security low. Unlimited
access to the print
system.
This client allows all users of the
workstation to install, delete, or
administer printers and print jobs on the
workstation, including printers and print
jobs of other users. By default, the iPrint
Printer List Web page installs this rpm.

1.3.1 Requirement
In order for iPrint to work properly, your workstation needs to have a Mozilla-based browser
such as Firefox, which is included with SLED. If it is not already installed, KDE users should
use YaST to install Firefox.
1.3.2 Procedure
You can install the iPrint Client during SLED installation or using YaST after SLED is installed.
•“Installing during SLED Installation” on page 10
•“Installing after SLED Installation” on page 10
Installing during SLED Installation
Shortly after the installation program begins, you can choose to install the iPrint client using the
following steps. You can also install the client later using the YaST Control Center.
1After selecting your preferred desktop, scroll down the list of Installation Settings and click
Software.
2Click Detailed Selection.
3Change the Filter to Search, and search for iPrint,
4Select the iPrint Client you want installed.
For more information about the iPrint Linux Client, see Section 1.1.2, “iPrint Client,” on
page 7 or contact your network administrator.

1Start YaST.
•GNOME:Click Computer > More Applications > System > YaST Control Center.
•KDE:Click the main menu button > System > YaST (Control Center).
