So first, I'm using the Mac product which is Qimage One. I only mention this, knowing you're on a Mac too in case this may differ from the other product under Windows.
You should be able to use both as according to the manual:
You can export images to Qimage One for printing from within any share-enabled macOS application. This includes Photos, Preview, Finder and other programs.
Don't use C1, can't comment about that part of the process but again, it should work.
