HP color laserjet 9500mfp Manuale Utente
Bidirectional communication depends on your network operating system and on the type of
connection you have between your computer and the HP color LaserJet 9500mfp.
connection you have between your computer and the HP color LaserJet 9500mfp.
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 driver's 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 color LaserJet 9500mfp 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 color LaserJet 9500mfp is
installed and an optional paper-handling accessory is added later, you can use the Update Now
feature to query the product and update the settings to match the product's configuration.

The Update Now feature triggers the driver to recheck 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 Unidriver.

NOTE
If you are using an HP PCL or PS unidriver, you must select Update Now through the
Automatic Configuration setting in 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.
