6.8.2 Printer Driver Uploading on OES 2 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.
6.8.3 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.
6.8.4 iManager Plug-Ins Are Platform-Specific
The iManager plug-ins are different for each server platform. Therefore, if you have both OES 2 and
NetWare 6.5 SP8 servers running iPrint services, you need two instances of iManager to manage
iPrint—one on each platform.
6.8.5 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 .
6.8.6 iPrint Disables CUPS Printing on the OES 2 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 LDAP—Preventing “Bad XML” Errors
If you are using Novell eDirectory 8.7.3x, timeouts are possible when you search from iManager for
eDirectory objects, such as NCP
TM
Server objects, Volume objects, and Cluster objects. This is
because the Object Class attribute is not indexed by default. The LDAP sub-tree search can take
over 30 seconds, which causes the query to time out. For example, a Cluster objects search from the
Cluster Options page returns the error:
