Sorry, if I confused you
Adobe Acrobat Reader
let's you edit text and print it out if the original PDF page has the form already incorporated into it.
So, let's say for example, I made bottlecap images that have backgrounds and I want to leave them blank so folks can add their own text. I can then save the file as a PDF file using Photoshop. I would then open up the PDF file in Adobe Acrobat Professional
and then use the tools in that program to make those blank areas into form fields. Then you save the file.
I can then distribute the PDF file and people can then use the free Adobe Acrobat Reader
to open the PDF file and add their text to those form fields and print them out. They will not be able to save the file, unless the person who made the original PDF file in Professional
has allowed them to.
I hope that helps explain it better.
