USB, TTP 7030
The USB (Universal Serial Bus) is an interface designed to handle peripherals daisy chained to
a single connector. The transfer speed is up to 12 Mbits/s, which is quite adequate for the
printer. Use this interface in operating systems with USB support, for instance Windows XP.
USB devices are Plug and Play compatible and hot swappable, which means that they can be
connected and disconnected without turning off the power, or rebooting the computer.
