Question, always on printing with plus42/free42

[nickapos]

Hi everyone, I have a question that might be naive so apologies in advance.
Is there any way to simulate the adding machine behaviour where it prints every new line added in the stack without me having to hit print manually?
In this case every time a new line is added to the stack?

The reason I am asking is because when I enter a collection of numbers and then sum them I can not go back and check if there was a typo.
When I was using an adding machine we would use the printout for this check.
Of course there might be a best practice for this that i am no aware of in which case I would be happy to learn.

Thank you very much
