ny2, i just recently sent N400 application which was accepted even though I had most of the information filled on the computer and some I had hand write because. The input boxes for the A#, SSN, some other were not working on the computer, so I did googled around and found that people have had that issue before and were suggested by USCIS officers that they could hand write where input field was not working on the computer.

I just wanted to let know that it does not have to either completely hand written or completely typed on the computer.

I am going to do the same thing with mine. I going fill whatever I can on the computer first, then print it and hand write the information that I couldn't type on the computer.
