Help creating fillable PDF over background layer

Hello!

I am trying to work on a project for a client. Basically - they'd like me to create a PDF version of a form they use that would require a dot matrix printer as it will have three layers (two carbon copies). Currently they use these forms with a typewriter but are looking to move away from using them. My thought was to import the current form as a background layer and lay the fillable boxes above it, so when they print they can hide the background layer and just print the text.

Is this even possible? Any ideas? Thank you for any insights. 🙂
