You could turn off antialiasing (extension of the stroke dialog under "line 
style") or use the pencil as "paint tool" there with a 1 pixel brush, these 
two methods look equivalent to me.  You might have noticed that you have full 
color pixels where the path goes straight across a pixel, but less when the 
pixel is only touchedm this is due to the antialiasing that's on by default.

This will give a fully colored, 1-pixel line:
 -------------------------
 | x-|---|---|---|---|-x |
 -------------------------

This will give a 50% colored, 2-pixel line:
 -------------------------
 |   |   |   |   |   |   |
 --x-------------------x--
 |   |   |   |   |   |   |
 -------------------------


I hope this helped a bit to understand the problem.

Greetings, Daniel
