HP CM8060/CM8050 Color MFP with Edgeline Technology - Software Technical Reference (external)

Bidirectional communication
In operating systems and 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 paper 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 CM8060/CM8050 Color
MFP with Edgeline Technology. 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
Windows 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 device.
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 device and automatically match the
print driver with the actual device configuration. EAC is activated during installation of the driver or
whenever the Update Now feature is used.
If the HP CM8060/CM8050 Color MFP with Edgeline Technology configuration 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.
Update Now
If the HP CM8060/CM8050 Color MFP with Edgeline Technology configuration has been modified
since installation, the driver can be automatically updated with the new configuration in operating
systems and environments that support bidirectional communication. Use the Update Now feature to
automatically reflect the new configuration in the driver. For example, if the device is installed and an
optional accessory is added later, use the Update Now feature to query the device and update the
settings to match the new device configuration.
The feature automatically updates the registry and changes the configuration information that appears
on the Device Settings tab of the HP PCL 6, PCL 5, and PS Emulation drivers.
NOTE: The Update Now feature does not have to be selected for the HP MFP Send Fax
driver to update.
Every time the HP MFP Send Fax driver is accessed, the driver automatically queries the print
driver to see if any changes have been made that would affect the HP MFP Send Fax driver
configuration. The HP MFP Send Fax driver is automatically updated with any changes.
