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: ● Upon installation of a print driver, when 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 4730mfp product 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 your network operating system and on the type of connection you have between your computer and the HP Color LaserJet 4730mfp. 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 your printing-system 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 29

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:
Upon installation of a print driver, when 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 4730mfp product is installed by using the Add Printer Wizard.

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 your network operating system
and on the type of connection you have between your computer and the HP Color LaserJet 4730mfp.
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 your
printing-system 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 pre-
existing 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
