Help updating a plugin to be compatible with Android 12 please

[PediaCalc1]

I have a app that depends on this plugin 'https://www.npmjs.com/package/cordova-plugin-zebraprinter' to print to a Zebra blue tooth printer. It is not compatible with Android 12. Wondering if anyone is able to update it?

Kind of depends on the issue but the plugin includes a closed source library: https://github.com/jesusbaqui/zebraprinter/blob/master/src/android/ZSDK_ANDROID_API.jar

So if the problem is in there, then there isn't much that can be done, unless if you know where that library is sourced.

Disclosure: I'm a self taught developer and half the time use trial and error and stumble upon a solution. So I am not sure what is happening in the code, but as the end user, I just get a pop up 'check that printer is on' - since updating to Android 12. I can go back to Android 10 in my config.xml and it works again.
Is any of that helpful?
