Well, if I print it once, to mail, then I print a copy for me. In addition, each state wants a copy of the Federal return, so it is a lot of copies! I prefer paper copies rather than email. I realize this is a lot of ink and paper... but having a paper copy saved my bacon with the IRS awhile back, so I stick with that. Also, with the 1040 form rather than the 1040 SR I can compare line by line with last year's taxes to see differences much easier.
