Software description has no bidirectional mode), it can only accept commands from the host and cannot report information back to the host computer. Bidirectional communication depends on your network operating system and on the type of connection that you have between your computer and your HP LaserJet 4345mfp. When you install the HP Toolbox, bidirectional communication is always enabled. Installing the HP Toolbox activates the HP Network Registry Agent (HPNRA) to ensure constant communication between your computer and the product. When you install a driver without installing the HP Toolbox at the same time, bidirectional communication is enabled only to configure the driver, and is then disabled unless the Update Now feature is used to update the driver. 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 bidirectionalcommunication software that allows it to communicate with the product and automatically match the print driver with the actual product configuration. EAC is activated during installation of the driver or whenever the Update Now feature is used. If the configuration of the HP LaserJet 4345mfp changes after installation, the driver can be automatically updated with the new configuration in environments that support bidirectional communication by using the Update Now feature. For example, if the HP LaserJet 4345mfp is installed and an optional media-handling accessory is added later, you can use the Update Now feature to query the product and update the settings to match the product configuration. The Update Now feature triggers the driver to check the registry for new information. The feature automatically updates the registry and changes the configuration information that appears on the Configure tab if you are using an HP Traditional PCL 6 or PCL 5 driver, and on the Device Settings tab if you are using an HP PCL 6, HP PCL 5, or HP PS Emulation Driver. NOTE If you are using an HP PCL or PS emulation unidriver, you must select Update Now through the Automatic Configuration setting on the Device Settings tab. If you are using an HP traditional PCL 6 or PCL 5 driver, you must click the Update Now button on the Configure tab. The Update Now feature is not available with the HP Traditional PS Emulation Driver. The following tables show the availability of EAC for various operating systems and network environments that support bidirectional communication. 30 2 Software description

has no bidirectional mode), it can only accept commands from the host and cannot report information
back to the host computer.
Bidirectional communication depends on your network operating system and on the type of
connection that you have between your computer and your HP LaserJet 4345mfp.
When you install the HP Toolbox, bidirectional communication is always enabled. Installing the
HP Toolbox activates the HP Network Registry Agent (HPNRA) to ensure constant communication
between your computer and the product. When you install a driver without installing the HP Toolbox
at the same time, bidirectional communication is enabled only to configure the driver, and is then
disabled unless the
Update Now
feature is used to update the driver.
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 actual product configuration. EAC is activated during installation of the driver or
whenever the
Update Now
feature is used.
If the configuration of the HP LaserJet 4345mfp changes after installation, the driver can be
automatically updated with the new configuration in environments that support bidirectional
communication by using the
Update Now
feature. For example, if the HP LaserJet 4345mfp is
installed and an optional media-handling accessory is added later, you can use the
Update Now
feature to query the product and update the settings to match the product configuration.
The
Update Now
feature triggers the driver to check the registry for new information. The feature
automatically updates the registry and changes the configuration information that appears on the
Configure
tab if you are using an HP Traditional PCL 6 or PCL 5 driver, and on the
Device Settings
tab if you are using an HP PCL 6, HP PCL 5, or HP PS Emulation Driver.
NOTE
If you are using an HP PCL or PS emulation unidriver, you must select
Update Now
through the
Automatic Configuration
setting on the
Device Settings
tab. If you are using an
HP traditional PCL 6 or PCL 5 driver, you must click the
Update Now
button on the
Configure
tab. The
Update Now
feature is not available with the HP Traditional PS Emulation
Driver.
The following tables show the availability of EAC for various operating systems and network
environments that support bidirectional communication.
