I’m researching different POS systems that run mainly inside a web browser, and I’m trying to understand how they handle receipt printing without installing native drivers.Some systems seem to rely on Epson’s ePOS protocol over HTTP, while others use custom local bridges or extensions. I’m especially curious about how they deal with:browser‑based printing limitationssending XML ePOS commandshandling raw bitmap images from the POSnetwork printers on local IPsIf you’re using a POS that runs in Chrome/Safari/Firefox and prints to a network thermal printer, how does it work in your case?

Does it rely on ePOS? A local agent? A custom API?Also, are there any Android‑based solutions that act as a lightweight print bridge for browser POS systems? Something that listens on HTTP and forwards ESC/POS to a printer?Not looking for recommendations to buy anything — just trying to understand how different systems solve this problem.Thanks!

Hey everyone,

​I'm an independent developer, and I see many small to medium businesses struggling with legacy attendance systems (like older ZKTeco devices running on local MS Access databases .mdb).

​The main pain points I usually see:

​Managers want cloud/remote attendance for field employees, but current cloud upgrades (like BioTime) are expensive or require buying new ADMS-supported hardware.

​Setting up Static IPs and Port Forwarding (Port 4370) for remote branches is a hassle and a huge security risk.

​HR completely resists changing their current local software because they are used to its specific payroll reports.

​I’m thinking of building a Hybrid Cloud Bridge. It’s a lightweight Windows service that runs in the background. It will sync approved clock-ins from a secure Employee PWA (with advanced anti-spoofing/GPS/WiFi verification) and inject them back into the local ZK Access database via port emulation.

​To the local software, the PWA acts exactly like a physical ZK device sitting on the network. No new hardware, no firewall port forwarding, and zero changes to the HR reporting routine.

​Before I write the first line of code, I want to know your honest feedback:

​Is this a real burning problem in your company or for your clients?

​What are the main limitations or edge cases I should worry about regarding MS Access databases or ZK protocols?

​Would you or your company pay a small annual fee ($49 - $99) for this bridge?

​Looking forward to your thoughts!

I built a lightweight ePOS printing bridge for Odoo that works without browser extensions.

The idea is simple:

Instead of installing complicated plugins or modifying Odoo POS heavily, the user only installs a small Windows print agent and sets the printer IP inside Odoo.

The agent emulates an Epson ePOS printer endpoint, so Odoo thinks it's talking directly to a compatible network printer.

Features:

Works with Odoo Community and Odoo.sh

No browser extensions required

Supports ESC/POS thermal printers

Local network printing

Fast and lightweight

Easy setup for restaurants and retail shops

One thing I focused on was making the installation simple enough for non-technical shop owners.

Currently testing it with multiple POS environments and it has been surprisingly stable.

I'm curious: Have you faced printing issues with Odoo POS before? What printing setup are you currently using?
