Zebra Printing Extension for Chrome
The Zebra Printing extension is a free tool designed for Chrome that facilitates direct printing of ZPL labels to network-connected Zebra printers. This extension is particularly beneficial for developers who need to integrate printing capabilities into their web applications without the complications of installing drivers or dealing with print dialogs. By utilizing the HTTP POST endpoint of most Zebra printers, users can print labels seamlessly from their web apps.
This extension addresses the common issue of CORS restrictions that prevent modern browser-based applications from accessing these printer endpoints. Developers can send print commands using the `window.postMessage()` method, specifying the ZPL string and printer URL. The extension listens for these messages and executes the printing process, while also providing a way to verify its installation through event messages, enhancing the overall user experience and functionality within web applications.
