First you have to check that your kernel has built-in the right options or you have the right modules compiled.
First you go to /usr/src/linux-2.x.xx and execute "make xconfig"
Go to the "Parallel port" and check that you have activated "parallel port support, Pc-Style support and IEEE 1284 support". Then go to Character devices and check that you have activated "Printer parallel support".
After that, recompile your kernel and check also that your BIOS has "EPP 1.9 mode" enabled.
PD: Donīt forget that if you decide to compile those options as modules, you have to include them in "modules.conf" under the /etc directory.
