so I have a Chrome App, which Google has deprecated and no longer supports, but I still have an app running in kiosk mode on Acer Chromebox that I have to support. I am trying to use the chrome.printProvider API to find a usb printer that is plugged in, and then simply print to it. With Google Cloud print also being deprecated, there is no viable print method. Not sure if I understand the API document or the setup required, and Google has removed majority of their Chrome App examples/samples. Where does the code go, into the background.js file? How would one set this up to listen for printers and then print using the print manager or even just silent print to the detected printer? Any help will be much appreciated as I am stuck since 15hours ago.
chrome.printerProvider.onGetPrintersRequested.addListener(listener: function)
