Thanks Vincent!
I guess I should have just looked in the parallel.c file.. Not being too
familiar with linux, I just assumed the port was forwarded to linux, I
didn't realize qemu had to code the transfer of data, and thus could easily
log it. Now that I think about it, that's pretty stupid of me to think.. :)
Thanks for setting me in the right direction.

Near the top of the file "hw/parallel.c", you can find the following line :
//#define DEBUG_PARALLEL
just uncomment it and rebuilt qemu, all parallel I/O will be written to
stdout. (or feel free to modify the printf traces)
