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 product 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. For more information, see
Update Now on page 20.
The following tables show the availability of EAC for various operating systems and network
environments that support bidirectional communication.
