Feature locking HP driver preconfiguration supports the ability to lock five settings: • Print on Both Sides (Duplex) • Print in Grayscale • Media Type • Paper Source • Output Bin When a feature is locked, the selected default option is the only option that is available to users. Generally, the feature is simply disabled in the driver UI after it has been installed. In Driver Configuration - Printing Preferences, for example, the Print on Both Sides (Duplex) setting has been locked to True. A small icon showing a padlock appears next to the setting in the UI. As a result, the user is unable to print from this driver on only one side of the page. If the driver is installed on a server, clients connecting to that printer are also unable to print on only one side of the page. Constraints The .CFG file is encoded with all of the same constraints that the drivers enforce. As a result, if the user attempts to set features to an invalid combination, a warning dialog box appears, and the feature change that triggered the warning is returned to its original state. For example, if the Media Type option is set to Transparency when Print on Both Sides (Duplex) is set to True, an Invalid Selection dialog box appears, as shown in Figure 5.
