Update the firmware The printer's various functions are controlled by software that resides in the printer, otherwise known as firmware. From time to time firmware updates will be available from Hewlett-Packard. These updates increase the printer's functionality and enhance its features. Firmware updates can be downloaded from the Internet and installed in your printer using the HP Internal Print Server: select Firmware update from the Main tab. Follow the instructions on your screen to download the firmware file and store it on your hard disk. Then select the downloaded file and click Update. The firmware includes a set of the most commonly used substrate presets. Extra substrate presets can be downloaded separately; see the User's guide.
