I'm not sure I understand what you are saying. The end-user is running Reader only, so they can't edit the fields. Plus, the copying to text fields defeats the purpose. They need the drop-down boxes for for certain pre-filled items, plus they need to be able to put in custom items as well.
Please let me know if I'm missing something. Thanks.
The end user won't have to do anything. You will need to set it up in Acrobat before sending the file to them, though, by adding a Will Print and a Did Print script, if you choose for the first option. And for the second option the text fields can be hidden to the user entirely, but printable, and set to copy the value of the drop-downs automatically, which will in turn be set to be visible, but not printable. These are the only ways of printing the file without the arrows that go with the drop-down fields.
