N400 one side printing or two side?

Ready to submit my application.
Do I need to print it single side or both sides (front and back)?
Thanks

Better to print on 2 sided.

[virudhun]

so I called the customer service. They said it is ok to print on single side.

I followed their instructions, applied, got appointment for finger print, and gave fingerprint. Now I am waiting for my interview date.

Hope this helps.

Printed one-sided and had no problems.

I was planning to print 2 sided, as I have to file applications for myself, wife and 2 daughters. Is it ok to print with "flip on long edge"? The instructions don't mention anything about printing.

Also, can I send all the applications in one envelope?
