Compact thermal printer, convenient to carry. - Model Name: MP-B20 - Type: Thermal Printer - Voltage: 3.7V - Current: 2.6A - Accessories: 2 rolls of paper, USB cable Thank you for viewing. Used for 2 years. It shows some signs of use, but I think it's still usable. I used it as a cash register for a small shop. Convenient to carry for temporary use at events, etc. It works with AirREGI (used as an app on iPad) to print receipts from the printer. You can set up your shop's logo, address, phone number, and invoice number printing in AirREGI. Even without AirREGI, there are various ways to use it. Although the manual is not included, you can find many usage instructions online by searching the product number.
