Weird, your paralle port can't do EPP when used directly, while it
works with ppdev.

Try tweaking the parport parameters in /etc/modules.conf :
alias parport_lowlevel parport_pc
options parport_pc io=0x378 io_hi=0x778 irq=7 dma=none
Another thing to try is to check is the kernel you use is
compiled with the followwing options in 'Parallel port support':
<M> Parallel port support
<M> PC-style hardware
< > Multi-IO cards (parallel and serial)
[*] Use FIFO/DMA if available (EXPERIMENTAL)
[*] SuperIO chipset support (EXPERIMENTAL)
< > Support for PCMCIA management for PC-style ports
[ ] Support foreign hardware
[*] IEEE 1284 transfer modes
What other parallel port BIOS setting do you have ?
