USB Host Port and
Link-OS Usage Examples
This section has information on using the printer’s USB Host port along with Link-OS features and Apps
(applications).
USB Host
The USB host port allows you to connect USB devices — such as a keyboard, scanner, or USB Flash
(memory) drive — to the printer.
USB Host Port Uses
• Firmware updates
• File transfers and management
• A port for low power USB data entry devices (keyboards, scales, scanners, and other wedge
devices).
Important • The USB Flash drive must be formatted with the FAT file system. Filenames may be 1 to 16 alphanumeric
characters (A, a, B, b, C, c, ..., 0, 1, 2, 3, ...) only. Only use ASCII characters. Do not use Asian characters, Cyrillic
characters, or accented characters in file names. Some functions may not work properly if there are underscores in a
file name. Use periods instead.
