A proxy server sits between a client and another server that the client is trying to communicate with. Often proxy servers are used in conjunction with a firewall to keep internal addresses private while exposing only the proxy server's address to external users. If you are using a proxy server and have users that need to submit print jobs through a proxy server, you can use the iPrint Client's Proxy setting. The client sends all print-related requests, like a print job, to the proxy server. The proxy server then redirects the print job to the correct iPrint server.
For example, Juan is a laptop user and has installed and printed to a variety of iPrint printers at the company's headquarters. While out on the road, Juan wants to submit a report to his boss. Rather than sending the report by e-mail or fax, Juan decides to send it to the printer near his boss. When he tries to send the report to the printer, he receives an error that the printer cannot be found. He knows that the company uses a firewall and a proxy server. He types the proxy server address in the iPrint Proxy settings, then tries to print the report again. This time the print job is accepted. The print job travels from his laptop to the proxy server. The proxy server redirects the print job to the printer's iPrint Manager, where the print job is spooled and forwarded to the printer.
To set the proxy server address in iPrint:
Click Start > Programs > Novell iPrint > iPrint Client Settings > Proxy.
Check the Use a Proxy Server for Printing check box, then specify its URL.
Click OK.
To disable using a proxy server, uncheck the check box.
You can set up iPrint on a terminal server to allow terminal server clients to install and print to iPrint printers.
Log in to the terminal server with Administrator or equivalent rights.
Install the iPrint Client.
The iPrint Client can be downloaded from the iPrint default page or by copying and executing nipp.exe from the iPrint server /var/opt/novell/iprint/httpd/htdocs/ippdocs.
NOTE: On terminal servers, the client auto update will not work. To update the client with a newer release, you must install it manually.
You can configure iPrint to work in any of of the following ways, depending on the rights the terminal server client has.
Install user printers only: User printers can be installed and deleted only by the user who installed the printer. User printers are not available to other users on the workstation. This is the default
Install workstation printers only: Workstation printers can be installed and deleted only by users with sufficient rights. After a workstation printer is installed, all users using the workstation can print to it.
Try to install workstation printer first: If the user has insufficient rights to install the printer, the printer is installed as a user printer.
To configure the iPrint for terminal server clients:
Log in to the terminal server with Administrator or equivalent rights.
Click Start > Programs > Novell iPrint > iPrint Client Settings.
Click Terminal Server, then select the configuration option you want.
Click OK.
The Novell iCapture LPT Port Redirector lets you capture LPT ports and redirect the output to iPrint printers. Novell iCapture is installed when you install the iPrint Client. Before using the LPT Port Redirector, you must have iPrint printers installed on the workstation and the iPrint Manager and Printer Agents must be up and running. This feature is not available on terminal servers.
For example, Olga uses a legacy MS-DOS application to run reports. The application can print only to an LPT port. With the iPrint Client installed, Olga installs an iPrint printer on her workstation and uses Novell iCapture to capture an LPT port. iCapture redirects any data sent to the LPT to the iPrint printer. Olga can now run her MS-DOS application from his her Windows workstation and send print jobs to an iPrint printer.
Click Start > Programs > Novell iPrint > iPrint Client Settings > iCapture.
Select the port you want to capture.
Click Select Printer, select the iPrint printer you want, then click Capture.
If the printer you want is not listed, check to see that the Printer Agent is up and running and that the printer has been installed as an iPrint printer.
Click OK.
You can also use the LPT Port Redirector to end a printer capture by selecting the port and clicking End Capture.
IMPORTANT: Existing port assignments are not displayed, and iPrint port assignments will supersede all other port assignments. iPrint port assignments remain in effect, even after the workstation restarts, until you end the capture.
Use the Passwords tab to manage passwords for iPrint.
Click Start > Programs > Novell iPrint > iPrint Client Settings > Passwords.
Select the realms you want to change.
Realms are directories, trees, or servers that you logged in to while the workstation has been up.
Use the buttons to perform the desired action.
Click OK.
