        Howdy, I have an HP5200C and HPDJ 696C on the same port... the trick
is to realize that ppscsi will work both with and without the parport modules.
But in order to share the port, parport has to be loaded... so:

        modprobe parport_pc // forces loading of the parport
                                        // sharing code
        modprobe epst // load PPSCSI driver
        modprobe lp // load normal printer support

        With this both the printer and the scanner should work. If one of
the lp or epst modules won't load, try loading the problematic one first. Only
one ordering will work for me (alas I forget which it is), if I try the other
way around I get resource busy errors when I try to load the second module.
