QZ Tray

Paket

Prints ZPL, ESC/POS or PDF from a web page via an app on the user's computer

Fiyat: Free, open source; paid support plans
Erişim: None; a paid certificate stops prompts

Hakkında

Open-source (LGPL-2.1) desktop app plus JavaScript library: a web page talks to QZ Tray on the user's computer to print ZPL, EPL, ESC/POS, PDF, HTML or images to local and network printers, and to read scales. Every workstation installs it; without a paid certificate users see trust prompts.

Neler yapabilirsin

Print ZPL labels to a Zebra printer from the browser on the user's computer
Print receipts to a thermal printer from a web POS without a print dialog
Read a USB or serial scale from a web app through the local QZ Tray app

Başlarken

Install QZ Tray on each computer that prints
Run npm install qz-tray
Connect, find the printer and send raw or PDF data

Örnek kod

const config = qz.configs.create(printer);
await qz.print(config, ["^XA^FO50,50^ADN,36,20^FDRAW ZPL EXAMPLE^FS^XZ"]);
