We are trying to print labels by sending RAW ZPL text from the browser(typically chrome) to the printer.
We are looking for the best way to handle Printing from Desktops/laptops/Tablets/Phone browsers over a wireless connection(or wired , as long as it's only in one solution).

Printing via java script(as suggested in the link below) does not work well(expecially with chrome) and with IE, the formatting is not right. JavaScript: Send raw text to printer - no server requests/method calls, able to work offline, purely clientside
Zebra seems to have provided a BrowserPrint functionality that resides, but that won't work with Android browsers
Installing 'Enterprise Browser' is not an option either, because we don't have control over what our clients use on their tablets.

So, is there a way/technology that lets us print from a webpage(java webapp) from browsers over a wireless connection from Desktops/laptops/Tablets/Phone? What's the best way to handle this?
