Which thermal printers work with Todebaran, and what to look for when buying one.

Todebaran prints to ESC/POS thermal receipt printers (and StarPRNT for Star models). This page lists the printer models it knows about and offers advice on choosing one. For setup, see Setting up a printer.

The Epson TM‑T20III and TM‑T20IV are reliable, widely available 80 mm printers and are a safe default — the TM‑T20III is Todebaran's out‑of‑the‑box model choice.

Supported models#

Choosing one of these in Settings → Printer → Model applies the right command language, paper width and cutting behavior for that printer.

Model not listed?

Most inexpensive receipt printers are ESC/POS‑compatible and clone a common model. If yours isn't in the list, pick the closest model from the same brand, or a generic entry (POS‑8360 for 80 mm, POS‑5890 for 58 mm), and run a Test print to confirm.

Paper width#

The model you choose sets the paper width — there's no separate width control. The two common sizes are:

  • 80 mm (about 48 characters per line) — the standard receipt size. Most Epson TM‑T20 and TM‑T88 models, and the generic POS‑8360.
  • 58 mm (about 32 characters per line) — smaller and cheaper. Generic models like POS‑5890 and Youku 58T.

Pick the model that matches the paper roll your printer actually uses; a mismatch prints too narrow or runs off the edge.

Connection support#

ConnectionSupported
Network (Ethernet / Wi‑Fi)Yes — the most flexible
USBYes
SerialYes
BluetoothOnly if the printer exposes a serial port (add it as Serial)

See Setting up a printer for the details of each.

Cutting#

Most listed models cut the paper automatically after each slip. A few basic 58 mm models (Youku 58T, MPT‑II) have no cutter — they simply feed the paper for you to tear off.

Buying advice#

If you're buying a printer for Todebaran:

  • Look for “ESC/POS” in the specs (Star printers use StarPRNT — also fine).
  • 80 mm is the safer choice — roomier layout and the most common paper.
  • Network is the most flexible for a shared printer; USB is simplest for one Mac.
  • When in doubt, an Epson TM‑T20III/T20IV just works.

A note on thermal paper

Thermal paper is coated with a developer; some contains BPA/BPS. If the printer is handled often, consider phenol‑free (BPA/BPS‑free) rolls.
