Driver Configuration
The HP LaserJet 2410, 2420, and 2430 print drivers feature bidirectional communication technology
which, in supported environments, provides automatic discovery and driver configuration for product
accessories. Accessories that are automatically discovered and configured include the optional 500-
sheet paper tray assembly (Tray 3), the duplexing unit for automatic two-sided printing, the printer
memory, and the job-storage features.
Automatic discovery and driver configuration through bidirectional communication occurs in the
following circumstances:
■ Upon every installation of a print driver, when using Enterprise Autoconfiguration (EAC)
■ When using the Update Now feature for a driver that is already installed
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 back information, such as what type of print media is available or what
accessories are connected to the product. 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.
Bidirectional communication depends on your network operating system and on the type of
connection you have between your computer and the HP LaserJet 2410, 2420, and 2430 printers.
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 printer. When you install a driver without installing the HP Toolbox at
