recommendation on a report generator for CI?

I spoke with a potential user of my system today. He wanted to know if there was a way to see a summary of the data. I am looking to write a report into a pdf. Since the data is a number of places including mysql and an AWS dbase, I will clearly need to do subtotals myself. Any report writers out there? I will need to set my logo on it, besides the totals.
