It seems he run into the :unscaled option.
the behaviour he is seeing is perfectly logical, and quite correct;

Let me explain.

When you zoom bitmap fonts (or better said; render them in higher pointsize)
then you can run into the problem that there are no bitmap fonts for the
size you are requesting.
Bitmaps of Times mostly go to 30pt or something.

Normally X scales the fonts for you, so you get (ugly) fonts which are of
the right size (well sorta...).
This behavior is not wanted anymore since we have vector fonts, and the
correct usage of bitmap fonts is only for quick on screen type. Fonts at
Other places, especially for print, should be vector fonts.

If you write a little program getting a font and then ask the width of the
font you can see that with bitmap fonts it sometimes does not get bigger.
See attachment 1.
When you remove the option in your XF86Config which tells X to not scale 
you can get larger bitmap fonts.
-    FontPath   "/usr/X11R6/lib/X11/fonts/misc/:unscaled"
+    FontPath   "/usr/X11R6/lib/X11/fonts/misc/"

after this; see attachment 2.

I am searching for a solution which simply does not allow the user to select
bitmap fonts at certain times. Perhaps when this option is enabled, or simply
in all applications which use the fonts to print as well.

All in all; bitmap fonts are _evil_ !!

The only thing worse than failure is the fear of trying something new
