Dynamically change field values in PDF from VB6 code

Hello.
I have a VB6 project where I have to print a lot of information about customers. Customer info is stored in Access DB. THe form itself is in PDF format. The PDF document has fields. What I want is to be able to dynamically fill those fields and then print the form with the changed fields. This task should be done with as little human interaction as possible.

What I have:
I have a ocnnection to the DB. I also managed to find code to print PDF object I created in my project. But I cant find a way to change fields inside that object.

Thanks in advance for any help.
