I can understand functionality as I am having a problem with Homebase and something I've done for YEARS.
Oh, you are a new user of PS?
I wouldn't change the Control Which Forms Print....will it even let you choose Never on the Filing Copy?
Mark your boxes like this, and then only the Preparer and Client copy will print, Print an entire return without using Print Preview and those settings will stay until you change them and print an entire return again.
But if client paper files, you'd have to manually change back.
