Printing From a Microsoft Windows NT 4 Application Server

The configuration needed to let users print from a Windows NT 4 application server depends on whether the Windows application object is configured to use the Microsoft RDP protocol or the Citrix ICA protocol. The configuration required for each of these protocols is described below.

Printing Using the Microsoft RDP Protocol

To print from an Windows NT 4 application server using the Microsoft RDP protocol, you have to configure an LPR-compatible TCP/IP printer on the application server that you want to print from. To do this:

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. Deselect the Automatically Detect My Printer check 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 SGD 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 is no close match, choose a PostScript printer.
10. When prompted as to whether the printer is shared with other network users, click Do Not Share This Printer.

Note The version of Microsoft RDP supported by NT 4 is not the same as the version supported by Windows 2000/2003 and so it requires the above configuration.

Printing Using the Citrix ICA Protocol

1. Configure an SGD printer queue on the UNIX application server that runs the ICA client.
2. Use SGD to log in to the Windows application server. Use the Citrix ICA protocol.
3. Start the Add Printer Wizard.
4. When prompted for how the printer is 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 SGD 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 is 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 SGD, change their default printer, and then log in again.
• Print jobs might be deleted - when a print job is transferred from the application server to an SGD server, the user's SGD 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 SGD users. If SGD 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 an SGD array.
