Recommendation letter-school form

Hey guys.
So I asked my teacher for recommendations.He agreed.
Now for the recommendation,should I ask my teacher to use a school form,with the school logo and stuff,so that it looks official?Or will the teacher’s signature be enough?

If you are applying through the Common App, your LoR writers will be asked to submit their letters electronically to the Common App. For other schools, I’d ask the teacher to use school stationary. Make sure he/she includes a phone number and email address. AO’s do occasionally want to communicate directly with LoR writers.
