Mastering JavaScript Receipt Printing Using POS Printer

Mastering JavaScript receipt printing involves circumventing the browser's security sandbox which prevents direct hardware access. The most basic approach utilizes `window.print()` combined with targeted CSS (`@media print`) to style an HTML document for the narrow format of a thermal printer. However, this method requires user confirmation for every print and lacks control over specific POS commands. For professional, silent printing, a more robust solution is required. This is typically achieved using a bridge application like QZ Tray or PrintNode, which runs locally on the user's machine. The JavaScript web application communicates with this bridge via WebSockets, sending raw printer commands (like ESC/POS) or structured data. The bridge then forwards these commands directly to the connected USB, serial, or network printer, enabling full control over printing, cutters, and cash drawer kicks. Alternatively, some modern network printers expose their own web service API (e.g., Epson's ePOS-Print), allowing JavaScript to send XML or JSON payloads directly to the printer's IP address for a seamless integration.
