"additional printer drivers required" dialogue appears on printer install when not needed

I'm using Ubuntu (Studio) 18.04, when I plugged my printer in, the printer installed without any issue (tested, confirmed working), but as the printer was installing an additional dialogue box appeared saying "additional printer drivers required", I pressed the button which said to "find in software" but of course it didn't find anything, I'm not sure why this dialogue appeared, but my printer installed fine.
