HP LaserJet Pro 300 and 400 Color M351 and M451 - Software Technical Reference

Figure 2-13 About tab
The About tab lists driver installation file names and their version numbers. The About tab also
indicates whether the driver was autoconfigured, whether administrator preferences were set, the
date the driver was last configured, and whether the configuration is autoconfigured or user-
configured.
The About button is also available on most driver screens. The About button provides a driver
version number and creation date.
Driver configuration for Windows
The HP print drivers feature bidirectional communication technology which, in supported
environments, provide automatic discovery and 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, product hard disk, and dual inline memory modules (DIMMs).
Driver autoconfiguration
Automatic discovery and driver configuration through bidirectional communication occurs in the
following circumstances:
●
When a print driver is installed by using the installer
●
When using the Update Now feature for a driver that is already installed
However, as shown in the following table, driver autoconfiguration and Update Now are not available
in Windows XP, Windows Server 2003, Windows Server 2008 and 2008 R2, Windows Vista, or
Windows 7 operating systems over a direct connection when the product is installed by using the Add
Printer Wizard.
