Note:
UB-U01II has bus-powered USB HUB. Therefore This USB model printer can’t be connected directly to
other bus powered HUB (including other USB model TM printer) and bus-powered function which
current consumption is over 100mA. If you would like to connect other USB model TM printer with
UB-U01II, use a self powered USB HUB as shown in the above figure.
The host PC needs to have an installed “USB device driver” for using USB model TM printer. Please
contact EPSON or your dealer about the USB device driver and the procedure for installing.
