Save pdf form as read only in reader 9

Question

I've spent the last 2 days looking over the internet and through the various menus on Adobe Acrobat 9 and Adobe Reader 9 and can't find a solution. I've made a form template in acrobat and it is to be opened by staff in my office using reader so they can edit the form fields and then save it as a non editable form if that makes sense. Reader will only allow it to save a copy, and when you do the form fields are still active form fields.
I've tried printing to pdf as a workaround but it just saves it as an image and you can't highlight the text anymore which is necessary for this template to work, (information on the form needs to be selectable as text information is copied into other documents at later date).
I really hope someone can help as this is driving me mad, and seems idiotic of Adobe to leave out such an obvious feature!

Answer 1

Thanks for that script, it is a great way of securing it from being edited, but reader still won't allow the form to be saved, only as a copy without the inputted text. The idea of what I'm trying to achieve is a form which the staff here fill out and then send to our customers with non editable fields, there is the option to print to pdf but that saves the file as an 'image', this stops people from highlighting text which we don't want, they have to be accessible afterwards to copy and paste the text at a later date.
I hope someone can help with what should be such a simple action.
