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.
The above clients do not affect installation of the iPrint Client, just access to the workstation print system. Also, these clients do not limit printing capabilities.
IMPORTANT: To install the iPrint Client you need root permissions. To upload drivers you from the system, you need to be defined with lppasswd; 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
During the installation of NLD Support Pack 2 or while using YaST to install the iPrint Client later, you select which client to install. For more information on the client installed on your NLD workstation, consult with your network administrator.
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.
