You don’t have to install drivers or CUPS on client devices. Linux and Android support IPP out of the box. Just make sure your CUPS on the server is multicasting to the LAN.
You may need to install Avahi on the server if it’s not already (that’s what does the actual multicasting). The printer(s) should then auto magically appear in the print dialogs on apps on Linux clients and in the printer service on Android.
On Linux it may take a few seconds to appear after you turn it on and may not appear when it’s off. On Android it shows up anyways as long as the CUPS server is on.
The problem is that the main container can (and usually does) rely on other layers, and you may need to pull updates for those too. Updating one app can take 5-10 individual pulls.
