Software description Windows printer-driver configuration The HP PCL 6 printer driver features bidirectional communication technology which, in environments that support the printer driver, provides automatic discovery and printer-driver configuration for product accessories at the time of installation. Some accessories that are automatically discovered and configured include the duplexing unit, optional paper trays, and dual inline memory modules (DIMMs). ● Printer-driver autoconfiguration ● Bidirectional communication ● Enterprise AutoConfiguration ● Update Now ● HP Web Jetadmin Printer-driver autoconfiguration NOTE: The 64-bit operating systems do not support printer-driver autoconfiguration. Automatic discovery and printer-driver configuration through bidirectional communication occurs in the following circumstances: ● When a printer driver is installed by using Enterprise AutoConfiguration (EAC) ● When the Update Now feature is used for a printer driver that is already installed However, as shown in the following table, printer-driver auto configuration and EAC are not available in 32-bit Windows operating systems over a direct connection when the printing-system software is installed by using the Add Printer Wizard. Direct connection is a parallel or USB port connection. Table 2-2 Availability of automatic discovery and printer- driver configuration through bidirectional communication in Windows Connection type Add Printer Wizard HP DIU Network Yes Yes Direct connection No Yes Bidirectional communication In environments that support bidirectional communication, the computer communicates with the product during installation, determines the physical configuration, and then configures the printer driver accordingly. Bidirectional communication is the capability of the product to respond to data inquiries from the computer, such as inquiries regarding the type of print media that is available and the accessories that are connected to the product. Bidirectional communication depends on the network operating system and on the type of connection that exists between the computer and the product. If the connection does not have this capability, the product can accept commands but cannot respond to data inquiries from the host computer. 42 Chapter 2 Software description ENWW
