Some questions about placecards

Ok, I feel stupid for asking this but...

Are you printing the names on your placecards? Or writing them out in script?

How are you writing them out? Mr. and Mrs. John Doe?
John and Jane Doe?

I did them on the computer (did not use the cards supplied by the hall).

I also went a more casual and did

John & Mary Smith

I am printing them out on my own computer with placecard paper I got from a stationary store.

I am going to write out Mr. & Mrs. James Doe - Table 2.

For a non married couple it will be Mr. John Doe & Miss Jane Doe - Table 2

I am printing mine and writing
Mr & Mrs John Doe
