Thanks!

If suission number on the form is enabled will it get printed on the
printout of the form that we print before submitting
...

Is it for the card form? If yes, I'm afraid it can't be shown on printout since it is hidden on the form and there's no way to alter its visibility since card form does not have CSS inject feature.

Alternatively, you can also use the random generator widget which is visible in the live form and on printout too.
