Okay... this is gonna be kinda long...
Note... that only a printer is connected to the parallel port... while
probing is performed for Paride devices... no Paride device is attached
to the parallel port... or to the printer...
There are four cases... in all these cases... parport_init,
parport_pc, parport_ieee1284, parport_procfs and parport_share... are
all compiled into the kernel...
1) lp compiled into the kernel
paride, pd, epat --- not compiled in kernel or as a module
In this case... the printer works normally
2) lp compiled into the kernel
paride, pd, epat --- compiled as modules
In this case... the printer also works normally... note... that nothing
has been added to conf.modules... in connection with pd and epat... so
i don't think the paride and/or pd and/or epat modules attempt to load
in this case...
3) lp compiled into the kernel
paride, pd, epat --- also compiled into the kernel
In this case... the printer prints garbage on boot
4) lp compiled as module
paride, pd, epat --- compiled into the kernel
In this case... the printer prints garbage on boot
Hope this answers all of your questions... for now...
Here is the dmesg output... for all four cases above...

So... as u can see... the printer printing garbage on boot... seems to
depend on whether paride, pd and epat... are compiled into the kernel..
