Hallo,

i can confirm your observation. I had the same impression comparing QTR 
and BlackOnly, but i think you cannot directly compare QTR and BlackOnly 
- it is comparing apples and pears as we say in germany. QTR is much 
smoother than BlackOnly which has a kind of more local contrast (as 
anyone said some weeks ago), therefore it looks sharper. Thus i\ufffdm not 
sure, whether QTR is really not as sharp as BlackOnly. I sometimes try 
to solve this issue with Qimage, but i never made systematical tests to 
find out if it is only a impression or really a difference between the 
different methods to print Black & White Images.
