2.5 USB connection
The TM printer can be connected to the host PC via a USB connector, and other TM printers can
be connected to the first printer via USB. (See “Changing the DIP Switch Settings” in Chapter 3
for DIP switch settings.)
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 UB-U01II equipped TM printer) and bus-powered function
whose 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.
When you would like to provide power from TM-U220 to a DM-D, you have to use “PS-180.“ The “AC
Adapter C” can’t provide power to a DM-D.
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.
