Parallel Port vs Device Driver Programming

Hello Folks ,

I just have a question here , how is programming a device which is
connected to a parallel port difference from writing a device driver
for an I/O device which is connected to the PCI Bus on the computer
with specific reference to UNIX / LINUX kind of OS .

ie how would programming be different in each of the cases .
I have some idea such as the Hardware address and IRQ and function
like
in() , out( ) etc and setting some terminal attributes.

Any body out there could elaborate with little bit more detail if and
how the programming
would be different in each of the cases (i.e one in which i have a
device connected to parallel port) the other in which the same or
similar is connected to the back plane PCI Bus etc.
Or am i missing some thing basic ?

Thanks
subra
