Paper saver that emulates server needed for BrowserPrint (Zebra ZPL)

zebra-emulator

Paper saver that emulates the service provided by BrowserPrint application (Zebra ZPL).

---

The BrowserPrint service application sends the ZPL to the Zebra Printer from the browser and we are intercepting those calls and logging them and optionally sending to a browser extension to view in real time (without using a physical printer or paper).

• This project logs what would be sent to the printer
• You can upload to an online viewer such as labelary or better yet, if you install the Zpl Printer Chrome browser extension and configure it to listen on port 9102. Once installed and turned on you will see the label(s) rendered in real time

HTTP service on 9100

HTTPS service on 9101 (with provided SSL cert)

To build the SSL keys and cert files, use command:

$ openssl req -nodes -new -x509 -days 7300 -keyout server.key -out server.cert

If you are printing a lot at once it may overflow your terminal/prompt. You can redirect to a file for easier searching/viewing:

$ yarn start > out.log

**NOTE: Makes use of ES Modules which require Node v14 or greater.
