Print 1099-NEC for subcontractor

I have entered 1099-NEC information for about 50 subcontractors. I went to print but they are all 1-up and my copy B and C forms are all 3 up. 

Can I simply print on plain paper and hand-deliver or mail them? No special form required??

 

The problem is I need to mail most of them and I don't have envelopes that fit the printout.

 

I plan to e-file to the IRS, but not sure how to get to my subs.
