slow parallel port


I'm currently working on a project that requires high speed data transfers
from and to the parallel port 0.
As a first try I want to use the standard parport driver and device
/dev/parpor0 (in EPP mode)
I've got data going out but the speed is about 115 KBytes/sec (measured
between the first data bit and the falling edge of the nwait).

According to the spec of EPP the transfer rates should be at least
500Kbytes/sec (up to 2MBytes/sec). What
am I doing wrong here. Is it the standard parport driver? am I missing a

Please help,
