Hi Stem,
I am using fcl-pdf and it works well for me as I like to have full control of the report. However much more hands on as you need to do all the coding for the reports.
I personally like this as it give complete control over the entire report head, body and footer.
If you prefer an easier way to product Pdf's then maybe a good report writer but you might need to pay $$$ for a commercial product.
NOTE fcl-pdf does need some improvements font size and placement on the page need work and I don't think anyone is actively developing.
Anyway I like the library and works for me to generate reports, invoices, statement etc. More work but more control.
Cheers Trevor
