Technology background information This chapter contains information about the following topics: ● Driver Configuration ● HP Driver Preconfiguration ● Euro character ● HP Embedded Web Server and HP Toolbox ● HP Embedded Web Server ● HP Toolbox ● HP Web Jetadmin ● HP Digital Sending Software ● Foreign Interface Harness ● Remote firmware update ● Printing print-ready documents from a command line ● Driver-feature comparison in various operating systems Driver Configuration The HP LaserJet 9040/9050mfp print drivers feature bidirectional communication technology which, in supported environments, provides automatic discovery and driver configuration for product accessories. Some accessories that are automatically discovered and configured include the duplexing unit, optional paper trays, and dual inline memory modules (DIMMs) Automatic discovery and driver configuration through bidirectional communication occurs in the following circumstances: ■ Upon installation of a printer 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 information back, 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 9040/9050mfp. Technology background information 27
