Unfortunately I need to be able to open an existing PDF and modify it. The reason is we leave records on site of how a customers equipment is configured and these records are considerably lengthy. I wanted to be able to do this electronically but still be able to update them.
The reason I want freeware is I need to be able to leave a copy of the program for others who follow me to use. I've seen the "printer" creators you referr to but unfortunately that doesn't help.
