For restaurants & installers

Check your POS. Test your printer.

Proxy Node Raw connects a supported USB ESC/POS receipt printer to software on your local Wi-Fi. Your POS must allow a manually configured raw network printer. Start with one test station: no commercial POS integration has been qualified, and the board needs suitable power, cabling and protection before use in a working restaurant.

Before you buy

Three checks before changing a working station.

A printer's brand name or an advertised discovery identity does not prove compatibility. Check the actual connection and print protocol first.

  1. Check the POS settings. It must accept a manually entered printer address and raw ESC/POS on port 9100, or you need an integrator using the HTTP API. A vendor-certified printer list is not bypassed by adding a node.
  2. Identify the exact printer. Record its model, USB interface and command set. StarPRNT-only and label printers are not yet supported. A CloudPRNT client is in development, implemented in firmware source but not yet in a released firmware image, and does not replace a CloudPRNT printer today. Check the tested hardware and limits.
  3. Test one complete station. Include receipt layout, cuts, paper-out recovery and a router restart. Drawer pulses on the raw print port are blocked; a drawer needs the separate HTTP endpoint and an integration that calls it. Read the supported integration recipe.

Budget for the board, printer, power, cables, any powered hub, physical protection and integration work. Current board availability and pricing are on the Proxy Node Raw page.

Local printing

Know what an internet outage will interrupt.

The node's local print path does not need internet access. Your POS may still need its own cloud service to accept orders, process payments or create a print job. Test its offline behavior before relying on it.

Internet unavailable

Local printing can continue if your POS still creates jobs and the node, printer and local network remain available.

Router or Wi-Fi unavailable

The POS cannot reach the node. Restore the local network and inspect job status before retrying, so you do not print duplicate tickets.

POS cloud unavailable

The node cannot restore order entry or payment services. Follow your POS provider's offline procedure and test it before service.

How it deploys

A node per station, not a server room.

A node sits beside the hardware it drives. It is a bare board; no mount or enclosure is included. Each station has its own node, but stations still depend on shared Wi-Fi, power and POS infrastructure. The diagram below is a possible layout to evaluate, not a qualified restaurant deployment.

Floor plan · one LAN, four stations

GET /peers — any node lists the whole fleet

Front counter

pn-7f3a.local

Receipt printer, with the drawer-kick pulse through the printer's RJ12 port

Kitchen line

pn-b21c.local

Kitchen printer — the node wraps and cuts tickets itself, at a measured 48 columns

Bar / takeout

pn-04de.local

Printer + barcode scanner together on one node, behind a powered USB hub

Host stand

pn-91a7.local

The old RS-232 scale or pole display nobody wants to replace (transport in development)

A station that needs a wired connection, 5 GHz Wi-Fi or several USB devices is what Station Hub, on presale is for.

Proven on hardware

Measured on real hardware, not projected.

Every number below was clocked on a real node driving real peripherals. Proxy Node Raw units ship with Nodeware 1.2.55 or later.

1,012 ms

Printer bound and ready

Through a powered USB hub, with a barcode scanner bound on the same node at the same time — and a real barcode delivered end-to-end.

0.15 s

Drawer-kick pulse

Measured tap-to-kick. It was 9–24 s before firmware 1.0.9 fixed Wi-Fi power save; now it's faster than the cashier's hand.

1 QR slip

Setup without a laptop

A new node opens its own setup Wi-Fi network and, with a printer attached, prints a QR slip to join it. Type the wrong password and it self-heals back to setup in ~3 minutes.
