3.13 Disable USB drive
You can use this option to disable the USB drive preventing somebody connecting a device to print or to scan
images.
3.14 Disable firmware update through USB
This option is used to disable the possibility of upgrading the printer by installing the firmware via a USB device.
3.15 Disable direct print using ePrint&Share
In some printers, when you connect a computer directly with a USB cable, you can print without installing any
driver. This can be done by launching the ePrint&Share application that resides inside the printer. This feature
can disable direct printing so that you cannot print through the USB unless you have the driver (or ePrint&Share)
installed in the computer.
3.16 Disable ePrint connectivity
This feature disables the ePrint Center functionality preventing somebody printing remotely to the printer.
3.17 Disable internet connection
Disable the direct connection of the printer to the internet. This option would also prevent the printer from
automatically performing firmware upgrades.
