Supported Printers

ReceiptKit works with Star Micronics thermal and impact receipt printers via the StarPRNT command protocol.

Connection Types

Ethernet (Recommended)

Connect your printer to the same local network as your Receipt Bridge PC. Printers are automatically discovered via mDNS and communicate over TCP port 9100. Most reliable connection method.

USB

Connect the printer directly to the PC running Receipt Bridge via USB cable. The bridge detects USB-connected Star printers automatically.

Tested and Recommended

For MVP launch, we officially recommend the Star Micronics mC-Print3 series. This is the printer family validated in real retail production environments.

mC-Print3 Series (Recommended)

80mm (3")

This is the series we actively test and run in retail production environments.

Models: MCP31L, MCP31LB, MCP31C, MCP31CBConnection: Ethernet, USB, Bluetooth (model-dependent)

Likely Compatible (Untested by ReceiptKit)

The models below are likely to work because they use StarPRNT / Star Line Mode, but we have not completed full production validation on them yet. Treat these as best-effort compatibility, not official MVP support.

TSP100 Series

80mm (3")

Untested by ReceiptKit. It probably works, but we do not currently guarantee behavior for this model in MVP.

Models: TSP143IIIBI, TSP143IIILAN, TSP143IIIW, TSP143IIIUConnection: Ethernet, USB, Bluetooth, Wi-Fi

mC-Print2 Series

58mm (2")

Untested by ReceiptKit. It probably works, but we do not currently guarantee behavior for this model in MVP.

Models: MCP21LB, MCP21LConnection: Ethernet, USB, Bluetooth

TSP650II Series

80mm (3")

Untested by ReceiptKit. It probably works, but we do not currently guarantee behavior for this model in MVP.

Models: TSP654IIConnection: Ethernet, USB

SP700 Series

76mm (3")

Untested by ReceiptKit. It probably works, but we do not currently guarantee behavior for this model in MVP.

Models: SP742, SP712Connection: Ethernet, USB

Paper Widths

Receipt Bridge automatically detects your printer's native paper width and renders templates at the correct resolution. You can also override the raster width in the API if needed.

Paper SizePrint Width (dots)Common Use
80mm (3")576 dots (203 dpi)Standard receipts, restaurant checks, retail
58mm (2")384 dots (203 dpi)Compact receipts, mobile POS
76mm (3")496 dots (203 dpi)Kitchen order tickets (impact printers)

Network Setup Tips

  • 1.Same subnet required — The printer and the PC running Receipt Bridge must be on the same local network subnet for mDNS discovery to work.
  • 2.Static IP recommended— Assign a static IP address to your printer via its configuration utility or your router's DHCP reservation. This prevents the printer's IP from changing after a power cycle.
  • 3.Firewall — Ensure TCP port 9100 is not blocked by your firewall between the bridge PC and the printer.
  • 4.Multiple printers — Receipt Bridge supports multiple printers simultaneously. Each printer is identified by its MAC address and can be targeted independently in print requests.

Don't see your printer model?

ReceiptKit uses the StarPRNT / Star Line Mode command protocol, which is supported by many Star Micronics receipt printers. If your printer supports Star Line Mode, it may work, but only the mC-Print3 series is currently validated and recommended for MVP. Contact us if you need help with a specific model. We're also planning support for additional printer brands (Epson, BIXOLON) in the future.
