Software description Driver Configuration for Windows The HP LaserJet PCL 6 and PCL 5 traditional drivers for Windows and the HP PCL 6, PCL 5, and PS emulation unidrivers 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 Enterprise AutoConfiguration (EAC) ● When using the Update Now feature for a driver that is already installed However, as shown in the following table, driver autoconfiguration and EAC are not available in Windows 2000, Windows XP, or Windows Server 2003 operating systems over a direct connection when the HP Color LaserJet 3800 printer is installed by using the Add Printer Wizard. Table 2-2 Availability of automatic discovery and driver configuration through bidirectional communication in Windows 2000, Windows XP, or Windows Server 2003 Connection type Network Direct connection Add Printer Wizard install Yes No Common installer Yes 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 media 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 3800. 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.
