You can use ZENworks to distribute the Novell iPrint Client and printers to users' workstations. Following the ZENworks instructions, you take a snapshot of a workstation before installing the client and another snapshot after. ZENworks creates a list of files to install and makes the necessary changes to the Windows Registry.
You could also use ZENworks to install an HTML file on the users' workstations that would take them to your iPrint Web site. This would save you from having to distribute a URL to your users. Many other implementations are at your fingertips depending on your specific needs. For more information on using ZENworks, see the ZENworks documentation.
