Wix-Based Self-Service Printing System Development

Automatic Self-Service Printing System (Wix + Razorpay + PrintNode Integration)

Project Description
I own a small printing shop and want to build a self-service printing system.
Customers will scan a QR code, upload files from their phone, choose print options, make payment, and then the printer should automatically start printing without manual intervention.

The frontend website will be built using Wix (As I already know a bit of Wix and can do basic changes on this).

I need a freelancer to build the backend automation + printer integration.

Customer Flow
Customer scans QR code
Opens Wix website
Uploads PDF / image

Selects:
Paper size (A4 / A3)
Color or B&W
Single / double sided
Copies
System calculates price

Customer pays using payment gateway (UPI / Card)

After successful payment:
File is sent automatically to printer
Printing starts on shop printer

No staff involvement for normal print jobs.

Technical Requirements
Frontend (Wix – I can help here)

File upload app - Uploadly

Print option selectors
Price calculation
payment checkout

Backend (You will build)

I need:
Download the uploaded file from Wix
Send file to cloud printer service
Trigger automatic printing

Use PrintNode for printer integration.

PrintNode desktop client will already be installed on my shop PC.

Logic -
Payment Success (cashfree webhook)
→ Backend server
→ Fetch file from Wix
→ Send to PrintNode API
→ Local printer prints automatically
