print : function => should wait for a promise

First we need to know if print is a promise.
According to this answer there is two possible ways we can do this:

• We can check wether or not print is a Promise (by checking if a then function is present in the object)
• We can blindly use Promise.resolve(print), which looks safer but could be more expansive

Either way we need to decide how to handle Promise case : should we maintain an internal state that indicate if we are loading, in error, printed, ... in our component? In this case promise resolution would update this state and trigger a re-render that would display the given component, while promise failure would update the state to trigger the display an error message. While promise is pending loading indicator should be display.

Thoughts?

The first implementation wasn't useful. We need to handle load function as a Promise. What do you think about it ?

I think the better way to think about new features is to think about use cases.
So... What are use cases here ?
Can you add an API usage example (how the future API that handle Promise would look like) ?
