i'm not 100% up to date on the topic nor a color / print specialist... 
but from what i used to hear in the past, consumer printer expect to get 
RGB (and the internally convert to CMYK for printing). so, if you feed 
them with CMYK, the driver will first convert the file to RGB and let 
the printer reconvert it to CMYK.

if this is true, no, it's not possible to print cyan only on a consumer 

i'd be interested in hearing from someone more knowledgeable than i am, 
if this is still true (or even if it has never been true).

on the other side, printing in color from a linux computer is a hit and 
miss... and printing from scribus is mostly a miss (except on windows). 
IMO not worth the try, except if it by chance it just works on your 
computer / printer.
this comes from my own experience on mac and linux (plus from reading 
many experiences by other people...)
