Description: I have running Red Hat 5.2 system with parallel port (and
printer attached to him) working properly.
I upgraded to Red Hat 6.1 and after trying to print something discovered
that printer is not recognized by the system.
I tried to add new printer using printtool and port probing failed.
I have recompiled the kernel with printer support in kernel (prev. it was
module i think).
After booting new kernel tries to load printer driver but unsuccessful (see
