Yes, I would agree. Have you looked at porting LCDHype to Linux?

BTW, the lcd4linux website says that using /dev/lp* doesn't work, so you
should try using /dev/parport* instead. Note that some distros
use /dev/parports/* while others, such as Fedora, use /dev/parport*

It should also be available via the /proc pseudo-file system. By default
drive z: is a symlink to /, so you can access /proc as z:\proc from
Wine. You can't see it in winefile for some reason and running 'dir' in
wine's command shell doesn't show it, but this Wine shell command works:

Z:\>type z:\proc\version
Linux version
(mockbuild at x86-1.fedora.phx.redhat.com) (gcc version 4.3.2 20081105 (Red
Hat 4.3.2-7) (GCC) ) #1 SMP Thu Dec 10 11:00:29 EST 2009


This means that you should be able to open the pseudo files in /proc
from  a Wine application and read their contents, which will give you
much of the system information that Linux utility programs can show.

It is also possible to run Linux programs via a shell: look in the Wine
wiki for details.
