Try "modprobe lp".  I'm surprised that it didn't get autoloaded by
kmod.  Are you using a custom kernel?

If you're using a 2.0.x kernel, the first printer device is /dev/lp1.
For all later kernels, it's /dev/lp0.

whinlatter:~# lsmod [trimmed]
Module                  Size  Used by
parport_pc             21408  1
lp                      8356  0
parport                33256  2 parport_pc,lp

Buried under /etc/modprobe.d/arch/i386, I have:

  alias char-major-6 lp
  alias parport_lowlevel parport_pc

A similar setup should have been automatically installed by your
distribution's module-init-tools/modutils package.  In this case,
Debian.

Roger
