Printing from a Microsoft Windows NT 4 application server

The configuration needed to allow users to print from a Microsoft Windows NT 4 application server depends on whether the application uses the Microsoft RDP or the Citrix ICA Windows protocol.

Configuring printing for applications that use the Microsoft RDP protocol

To print from an application that uses the Microsoft RDP protocol, you have to have to configure an LPR-compatible TCP/IP printer on the application server as follows:

1. Log in to the application server as a Windows administrator or a member of the Administration group.
2. In Windows Control Panel, double-click Network.
3. In the Services tab, click Add to install the Microsoft TCP/IP service.
4. Run the Add Printer Wizard on the application server to configure the new printer.
5. When prompted, click Local Printer. Clear the Automatically Detect My Printer box.
6. Click Create A New Port and then click LPR Port.
7. In Name Or Address Of Server Providing lpd, type the full DNS name of the primary Secure Global Desktop server in the array.
8. In Name Of Printer Or Print Queue On That Server, type tta_printer.
9. When prompted, choose the printer model and manufacturer that most closely matches the client device's default printer. If there's no close match, choose a PostScript printer.
10. When prompted as to whether the printer will be shared with other network users, click Do Not Share This Printer.

Note This configuration is necessary because the version of Microsoft RDP supported by Windows NT 4 is not the same as the version supported by Windows 2000/2003.

Configuring printing for applications that use the Citrix ICA protocol

To print from an application that uses the Citrix ICA protocol, you have to configure a Secure Global Desktop printer on the UNIX server running the ICA client and on the Windows application server. You do this as follows:

1. Configure a Secure Global Desktop printer on the UNIX application server that runs the ICA client.
2. Use Secure Global Desktop to log in to the Windows application server. Use the Citrix ICA protocol.
3. Start the Add Printer Wizard.
4. When prompted how the printer should be managed, click Network Printer Server.
5. In the Connect to Printer box, double-click the Client icon.
6. In the Shared Printer list, double-click the printer you want to configure. The name of the printer you need to select has the format ip_address:#printer_name, where ip_address is the IP address of the primary Secure Global Desktop server in the array and printer_name is the name of the printer you configured on the UNIX application server.
7. When prompted, choose the printer model and manufacturer that most closely matches the client device's default printer. If there's no close match, choose a PostScript printer.

Limitations

Printing from a Windows NT 4 application server has the following limitations:

• No multiple printer support - you can only print to the client device's default printer. It is not possible for users to select a printer. If a user needs to print to a different printer, they have to log out of Secure Global Desktop, change their default printer and then log in again.
• Print jobs may be deleted - when a print job is transferred from the application server to a Secure Global Desktop server, the user's Secure Global Desktop name is needed to identify which client device to sent the print job to. With Windows NT 4 there is no direct way to associate print jobs with Secure Global Desktop users. If Secure Global Desktop cannot identify which user has printed a particular job, the print job is deleted. This might happen, for example, if two users log in to the application server with the same name.
• Distributed printing is not available - all print jobs are directed through the primary server in a Secure Global Desktop array.
