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?
