Awesome Web Printing

A curated list of resources, libraries, SDKs, standards, and examples for printing from modern web applications.

Why this repository exists

Printing from web applications is still one of the least documented areas of modern software development.

Developers often need to:

• Print receipts
• Print shipping labels
• Print invoices
• Print kitchen tickets
• Print barcode labels
• Connect to thermal printers
• Print silently
• Communicate with local devices

Unfortunately, there is no single place that documents the ecosystem.

This repository aims to become that place.

Browser Printing

Native Browser Printing

• window.print()

Pros

• Built into every browser

Cons

• Print dialog always appears
• No printer selection
• No raw printing
• No silent mode

---

Silent Printing

Silent printing generally requires:

• Local runtime
• Native application
• Browser extension
• Enterprise policies
• Kiosk mode

Why browsers restrict printing.

Localhost APIs.

Native runtimes.

Certificates.

Code signing.
