Do you already use in /etc/cups/cupsd.conf
   LogLevel debug
perhaps together with
   MaxLogSize 0
(restart the cupsd after changes in its cupsd.conf)?

Regarding input and output data it is a bit more tricky.
You may exchange step by step each filter binary by a
selfmade script which writes its input into a file.
