The mass storage feature supports ".bin" and ".blf" files.
This feature is useful in the following situations:
When you want to apply settings that are stored in a command file (".bin" format) or templates that are stored in ".blf" format files distributed by the administrator without using a customized tool.
When you want to execute commands without installing the print driver.
When you want to use a device with an OS (including non-Windows operating systems) that has a USB host feature to print and transmit data.
