Software description Windows driver configuration The HP PCL 6, PCL 5, and PS emulation drivers feature bidirectional communication technology which, in environments that support the drivers, provide automatic discovery and driver configuration for device accessories at the time of installation. Some accessories that are automatically discovered and configured include the duplexing unit, optional paper trays, and dual inline memory modules (DIMMs). Topics: ● Driver autoconfiguration ● Bidirectional communication ● Enterprise AutoConfiguration ● Update Now ● HP Driver Preconfiguration Driver autoconfiguration NOTE: The 64-bit operating systems do not support 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 Vista, Windows 2000, Windows XP, or Windows Server 2003 (32-bit) operating systems over a direct connection when the HP Color LaserJet CM4730MFP is installed by using the Add Printer Wizard. Direct connection is a parallel or USB port connection. Table 2-2 Availability of automatic discovery and driver configuration through bidirectional communication in Windows Vista, Windows 2000, Windows XP, or Windows Server 2003 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 device during installation, determines the physical configuration, and then configures the driver accordingly. Bidirectional communication is the capability of the device 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 device. Bidirectional communication depends on the network operating system and on the type of connection that exists between the computer and the HP Color LaserJet CM4730MFP. 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.
