My Epson U220 doesn’t work with my Aloha system. What could be going on?
By: POSGuys Support - 8/4/2017

With the Aloha POS system, it is recommended by the manufacturer of the software to use an RS-232 interface (serial) on the <a href="https://posguys.com/receipt-pos-printer_12/Epson-TM-U220_502/C31C514653_3119/">TM-U220B</a> impact printer. If you have an Ethernet or USB enabled U220, you should be able to swap out the interface cards with your old printer, or you may order a new printer. Once you have the serial interface installed (if it didn’t already come with it), plug in the serial-to-Ethernet adapter on the back of the device.

One additional step that you may need to follow, is to modify the DIP switches on the bottom of the printer. This can be done by performing the following adjustments on the switch banks:

**TMU220B – Serial
DSW1: All Off
DSW2: 2 On and All Others Off**

After making the aforementioned adjustments, your printer should be operational with Aloha POS.

If you have any further issues with setting up the printer, feel free to contact POSGuys Technical Support team at **Support@posguys.com** or via phone at **1-800-903-6571 ext 302**.
