What are the files in the /Library/Image Capture/TWAIN Data Sources/ and can they be removed?

In preparation for macOS 10.15, I'm reviewing my list of installed applications and removing those that are 32-bit. On the list of apps identified by System Report , I see two things that are 32-bit: * Canon MP530.ds * Canon MP600.ds Both of them reside in /Library/Image Capture/TWAIN Data Sources/, and they are the only contents of the folder. These look like printers, but I have no idea if I ever installed those models. The "Last Modified" dates are nearly a decade ago. What are these files for, and is it safe to remove them?
