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
