I do use iCloud for files, notes, contacts, calendars ... Let me elaborate ...
I handle finances from my Mac. Occasionally I have to prepare a paper deposit slip with dozens of check entries. The Calculator app does have a paper tape "feature", but it's useless for this purpose. I presents multiple items per line separated by + signs. Without making an exhaustive search, I have not yet found a Mac app to do what I need.
However, a quick search of the iPad App Store turned up exactly what I want for $4. I would like to open a window on my Mac showing the iPad, run the app there to prepare my tape, and print it (via AirPrint) to the printer beside my Mac.
