6.9 iPrint

iPrint has the following implementation caveats:

6.9.1 Advanced Printing Options

Some drivers, such as HP and Lexmark UPDs, have problems handling advanced printing options, such as watermarks and n-up printing when they are used from user workstations.

6.9.2 Authentication Dialog Not Displaying for Secure Printers from Terminal Servers

When you perform an automatic driver or profile update for secure printers from terminal servers, the authentication dialog box is not displayed.

6.9.3 Cluster Failover Between Mixed Platforms Not Supported

Clustered iPrint services can only fail over to the same platform, either OES or NetWare.

6.9.4 iManager Plug-Ins Are Platform-Specific

The iManager plug-ins are different for each server platform. Therefore, if you have both OES and NetWare 6.5 SP8 servers running iPrint services, you need two instances of iManager to manage iPrint—one on each platform.

6.9.5 iPrint Client for Linux Doesn't Install Automatically

Users who are used to installing the Windows iPrint Client expect to choose an Open option and have the client install automatically. However, installing the client on Linux workstations requires you to save the RPM package and then install it manually if a package manager is not already installed and configured as it is in the Novell Linux Desktop. For more information, see Linux: iPrint Client in the OES 11 SP2: iPrint Linux Administration Guide.

6.9.6 iPrint Disables CUPS Printing on the OES Server

iPrint uses CUPS to render print jobs before sending the print job to the Print Manager. For performance and scalability, printing from the server itself is disabled during the OES installation of iPrint.

6.9.7 Linux and Macintosh Client Printer Installation Fails When Communicating via Proxy

Linux and Macintosh iPrint clients fail to install printers when communicating with the iPrint server through a proxy server.

6.9.8 Printer Driver Uploading on OES 11 SP2 Might Require a CUPS Administrator Credential

A PPD is the Linux equivalent of a printer driver on Windows.

There are two versions of the iPrint Client: high security and low security. End users and administrators install the high-security client when using the iPrint Printer List Web page.

This means that administrators are prompted for a CUPS administrator credential when uploading PPDs. However, the prompt doesn’t specify that a CUPS administrator credential is needed and the root user credential does not work.

6.9.9 Printer Driver Uploading Support

Uploading drivers from SUSE Linux Enterprise Desktop (SLED) 10 supports PPD upload using Add From System but SLED 11 supports PPD upload using both Add From System and Add From file.

Uploading PPD printer drivers from a Windows workstation requires Internet Explorer 5.5 or later and supports only Add From File."

Windows printer drivers can be uploaded only by using Internet Explorer running on Windows.
