We have a web application that mainly works on iOS Safari and Windows Chrome. Our client requires us to retrieve labels in PDF and ZPL and then print them to a label printer.

Our current logic is:

1. Webapp retrieves the PDF/ZPL file and then sends it to web browser printer in Safari iOS or Windows Chrome.
2. Label preview is shown and user clicks to print.
3. Label is printed.

We are aware of the solution using SendFileToPrinter API and Zebra Savanna, in which we should connect the printer through a wired or wireless network connection.

We are also aware of the solution using BrowserPrint App and javascript library to print labels from a Mac, Windows, or Android environment, however, there is no support for iOS devices.

Is there any other way to connect the printer through Bluetooth connection (using an iPad - iOS, for example) and print labels in PDF or ZPL from our browser-based web application like using any other normal printer?
