If you're outfitting a checkout counter, the choice between two Epson thermal receipt printers isn't just about the brand-it's about how your register connects and what you're willing to pay. Both of these used units are Epson printers, but they offer different connection options and prices. Thermal receipt printers are a core part of any register setup, and both of these Epsons come from used listings, so the connection options should drive your decision. The TM-T20III leans heavily on Square compatibility, while the TM-T88V offers extra connection options.
Quick Verdict
For a Square-based retail counter, the Epson TM-T20III at $69.99 is the clearer pick because it's designed to work with Square Stand and Square Register. For a more flexible setup that needs more than a basic wired hookup, the Epson TM-T88V at $65.95 is the lower-priced unit by $4.04. If you're not using Square, the TM-T20III's main selling point disappears, and the TM-T88V's extra connection option becomes more useful.

Where Each Printer Wins
Epson TM-T20III wins if your point of sale is Square. It works with Square Stand and Square Register, but only over a wired connection. It also comes with an OEM Epson C1 power supply, though you'll need to supply your own USB cable. If you don't mind a wired-only setup and want a printer that's Square-ready, this is the one.
Epson TM-T88V wins if you want more connection options or want to spend a little less. It adds an extra connection option, and it's aimed at retail, restaurant, and hospitality POS work. That extra port can be a lifesaver for mixed hardware setups.
Product Notes
Epson TM-T20III
If your register runs Square, this used printer is worth a close look. It's compatible with Square Stand and Square Register, but only when connected by wire. That makes it a direct, no-nonsense choice for a Square-based counter. The package includes an OEM Epson C1 power supply, which is one less thing to buy, but note that no USB cable is included, so you'll need to add your own. The TM-T20III uses monochrome thermal printing and is compatible with Windows. If the printer doesn't connect on the first try, the instructions suggest updating the Square app. That's a small but practical tip for a busy register. If you're already using Square Stand or Square Register, this printer is designed to drop into that setup.
Epson TM-T88V
This used Epson TM-T88V, model M244A, is built for POS work across retail, restaurants, and hospitality. Its headline advantage here is connectivity: you get a conventional wired connection plus a serial port, which gives you more flexibility if your checkout setup mixes modern and legacy gear. The power supply is included, so it's ready to plug in once you have the right cable. It supports 80mm receipt paper, the standard width for many retail and food-service printers. One thing to keep in mind: the unit is sold without a manufacturer warranty. That doesn't change what the printer can do, but it's worth factoring into your buying decision. If you need a backup printer for a busy counter, the extra serial port might be the tiebreaker.
Final Choice by Use Case
Choose the Epson TM-T20III if your POS is Square and you're okay with a wired connection-just remember to grab a USB cable.
Choose the Epson TM-T88V if you want extra connection options, plan to use it in a retail or restaurant setting, and like the idea of a lower-priced Epson. Just be comfortable with the no-warranty situation. Think about whether your counter is already set up for Square or if it needs to talk to a mix of hardware.
