Driver Configuration for Windows The HP print drivers feature bidirectional communication technology which, in supported environments, provide automatic discovery and driver configuration for product accessories at the time of installation. Some accessories that are automatically discovered and configured include the duplexing unit, optional paper trays, printer hard disk, and dual inline memory modules (DIMMs). Driver autoconfiguration Automatic discovery and driver configuration through bidirectional communication occurs in the following circumstances: ● When a print driver is installed by using the installer ● When using the Update Now feature for a driver that is already installed However, as shown in the following table, driver autoconfiguration and Update Now are not available in Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, or Windows Vista operating systems over a direct connection when the HP Color LaserJet CP3525 Series product is installed by using the Add Printer wizard. Table 2-1 Availability of automatic discovery and driver configuration through bidirectional communication in Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, or Windows Vista Connection type Add Printer Wizard install Common installer Network Yes Yes Direct connection No Yes Bidirectional communication In environments that support bidirectional communication, the computer communicates with the product during installation, determines the physical configuration, and then configures the driver accordingly. Bidirectional communication is the capability of the product to respond to data inquiries from the computer and report information back, such as what type of print paper is available or what accessories are connected to the product. Bidirectional communication depends on the network operating system and on the type of connection that exists between the computer and the HP Color LaserJet CP3525 Series. If the connection does not have this capability (that is, if it has no bidirectional mode), it can only accept commands from the host and cannot report information back to the host computer. Enterprise AutoConfiguration Enterprise AutoConfiguration (EAC) uses bidirectional communication to provide autoconfiguration functionality for installation of the print driver over a network, whether you use the installer on the printingsystem software CD or the Add Printer wizard to install the driver. Driver installation that includes EAC is configured with the same settings as the physical configuration of the product. Configuration occurs without user interaction. If bidirectional-communication software has been installed previously, EAC is not activated, and the preexisting bidirectional-communication software is used to configure the print driver. If bidirectional communication software has not been installed, EAC installs bidirectional-communication software that allows it to communicate with the product and automatically match the print driver with the ENWW Driver Configuration for Windows 27
