printer error

when I first downloaded the software, as well as when I was trialing it I had no problem printing now after editing a photo it tells me I have to set up my printer except for the fact that there is no place that I see to set my printer, not to mention it printed right to that printer before. If I print from organizer without editing I have no issue. Which defeats the purpose of being able to edit a photo.

How do I fix this?
