Thanks. Now I understand what the DVI files really are.

Yes, of course, now I understand that. The devices themselves are 
different so nothing can be perfectly device-independent...

And they really are excellent. When I found TeX I had no typesetting 
background at all, the whole experience with printing text I got was 
using Microsoft Word and similar products. The results I get now are 
truely amazing. I can make my own documents looking just like Donald 
Knuth's The Art of Computer Programming, which is something still hard 
to believe...

Tomas Rokicki was kind enough to aks me for my test files and he has 
already told me what I was doing wrong. I was using a non-standard font 
size, which caused dvips to use bitmap fonts instead of Type 1 even with 
-Pcmz switch. So the problem is already solved. But I think it could be 
a good idea to join GUST anyway. Thanks.
