Your code is very strange. An outsider seeing the code out of context

What makes you think this will result in valid PDF syntax?

Maybe it is written, but not visible when you open the file in Adobe Reader.

What is the docInfo property?

What is docinfo? Is it a dictionary?
What is "IP_Text"?

What is ipText? Is it valid PDF syntax?
Isn't it extremely dangerous to append a snippet of PDF syntax like this?
What are you trying to achieve?

Aha, docinfo is a dictionary. More specifically: metadata.
You're using a method to add more metadata in an attempt to remove
metadata...
Also: you are adding some existing metadata to the content stream of a page.
I have no clue about what you're trying to achieve.
I only have an opinion: what you're doing is dangerous. I wouldn't do it.
