This parameter specifies whether a printer session will prompt the user for a device name when a connection is requested. Because the normal behavior of printer sessions varies, the results of setting this parameter are also slightly different depending on the type of printer session involved.
In an IBM 3270 Printer session, the normal behavior is to prompt the user for a device name (promptForDeviceName is true). If you set promptForDeviceName to false, you must either save the device name in the configuration or user preference file or provide some other method for the host to locate a printer device
In an IBM AS/400 Printer session, normal behavior is not to prompt for a device name (promptForDeviceName is false) but to cycle through all printer devices to find one that is available. If the parameter is set to true, the session prompts the user for a device name.
