iPrint has the following implementation caveats:
Section 6.8.2, Authentication Dialog Not Displaying for Secure Printers from Terminal Servers
Section 6.8.3, Cluster Failover Between Mixed Platforms Not Supported
Section 6.8.5, iPrint Client for Linux Doesn't Install Automatically
Section 6.8.6, iPrint Disables CUPS Printing on the OES Server
Section 6.8.7, Linux and Macintosh Client Printer Installation Fails When Communicating via Proxy
Section 6.8.8, Printer Driver Uploading on OES 11 SP3 Might Require a CUPS Administrator Credential
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.
When you perform an automatic driver or profile update for secure printers from terminal servers, the authentication dialog box is not displayed.
Clustered iPrint services can only fail over to the same platform, either OES or NetWare.
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.
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 SP3: iPrint Linux Administration Guide.
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.
Linux and Macintosh iPrint clients fail to install printers when communicating with the iPrint server through a proxy server.
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.
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.
