6.7.1 Cluster Failover Between Mixed Platforms Not Supported

Clustered iPrint services can only fail over to the same OES 2 platform (Linux or NetWare).

6.7.2 Printer Driver Uploading on OES 2 Linux 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. By default, 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.

6.7.3 Printer Driver Uploading Support

Uploading PPD printer drivers from a Linux workstation requires a Mozilla^*-based browser. Only the Add From System button works for uploading drivers. Non-Mozilla-based browsers, such as Konqueror, cannot be used to upload drivers.

Uploading PPD printer drivers from a Windows workstation requires Internet Explorer^* 5.5 or later. Other browsers running on Windows do not work for uploading drivers.

Windows printer drivers cannot be uploaded by using Mozilla-based or other browsers on any platform.

6.7.4 iManager Plug-Ins Are Platform-Specific

The iManager plug-ins are different for each server platform. Therefore, if you have both OES 2 Linux and OES 2 NetWare servers running iPrint services, you need two instances of iManager to manage iPrint—one on each platform.

6.7.5 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 2 SP2: iPrint for Linux Administration Guide.

6.7.6 iPrint Disables CUPS Printing on the OES 2 Linux 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.
