4. Kernel printer devices
There are two completely different device drivers for the parallel
port; which one you are using depends on your kernel version (which
you can find out with the command uname
-a). The driver changed in Linux 2.1.33; essentially all
current systems will be running kernel 2.2 or later, so you'll
probably want to skip ahead to the parport driver section.
A few details are the same for both styles of driver. Most
notably, many people have found that Linux will not detect their
parallel port unless they disable "Plug and Play" in their PC BIOS.
(This is no surprise; the track record for PnP of non-PCI devices
with Windows and elsewhere has been something of a disaster).
