Odoo 18  ·  Native Module
Nexus  POS Multi-Printer

Let a specific browser or device print receipts on its own local Epson ePOS printer — without touching the shared POS session, the cash drawer, or who can close it.

Per-Device Routing Session Untouched One Console Command Fully Reversible
Pure Frontend, Zero New Fields · Works With pos_epson_printer · Safe Try/Catch Fallback

Imagine you just brought in a new POS device for your second cashier. You want it to connect to its own printer — but stay on the exact same POS session as everyone else, so the manager still controls closing the session and collecting cash.

The problem: Odoo only lets you set one printer IP per POS Configuration. So normally, that new device would try to print on the first cashier's printer instead of its own.

This module fixes exactly that.

Why You Need This

Odoo's Point of Sale only stores one receipt-printer IP per POS Configuration. Here's what that means in practice.

Without This Module
  • Only one receipt-printer IP can be set per POS Configuration
  • A second device sharing the same session has no way to print on its own printer
  • Splitting into separate POS sessions just to get a second printer breaks shared cash control
  • No native, supported way to override the printer per browser
With This Module
  • Each device prints on its own local Epson printer, with one console command
  • The shared POS session, cash drawer, and session-closing rights stay exactly as configured
  • Every other device keeps printing on the printer already set in POS Configuration
  • Override applies regardless of which employee is logged in on that device

How It Works

A small, focused module that does exactly one thing safely.

 

Per-Device Printer Override

A single localStorage key, set once in the browser, tells that specific device to print receipts on its own printer IP instead of the one in POS Configuration
 

Shared Session Stays Untouched

No changes to pos.session, pos.config, the cash drawer, or who can close the session. Every device keeps logging into the same shared POS session as before
 

Safe Fallback by Design

The override logic is wrapped in try/catch. If anything goes wrong, it logs to the console and falls back to Odoo's normal printer behaviour instead of blocking POS startup
 

Fully Reversible

Clear the localStorage key, or simply uninstall the module, and the device returns to Odoo's stock printer behaviour with nothing left behind
 

Independent of the Logged-In Employee

The override is tied to the browser, not the user. Any employee logging into that device prints on the printer set for it
 

Lightweight, Frontend Only

No backend Python logic, no migrations, no new database tables. Just one JS override on top of pos_epson_printer

Setup — One Command, One Time

            Browser Console — Setting the Printer Override
Browser console command
Setup

The Set Override command running in Chrome DevTools on the second device
Set the override
localStorage.setItem("nexus_pos_receipt_printer_ip", "192.168.x.x")
Remove the override
localStorage.removeItem("nexus_pos_receipt_printer_ip")

Reload the POS tab after running either command. Replace the IP with that device's own Epson printer IP.

Technical Notes

 

Built on pos_epson_printer

Extends Odoo's own ePOS printer extension point. Requires the pos_epson_printer module, included with standard Odoo.
 

No Data Model Changes

Zero new fields on pos.order, pos.session, or any accounting model. Nothing here can affect data integrity.
 

OWL Native for Odoo 18

Patches the POS frontend's PosStore through the standard OWL override mechanism. No deprecated APIs.
 

Try/Catch Wrapped

If the override fails for any reason, it logs to the console and silently falls back rather than blocking POS startup.
 

Any Deployment

Works on On-Premise, Odoo.sh, and Docker deployments. No server-side configuration needed after install.
 

Clean Uninstall

Uninstalling fully reverts behaviour to stock Odoo. No leftover config, no orphaned data.
