Digital BW, The Print

Previously I have been shooting with a D100. Due to a few "quirks" as 
I'll call them I decided to go back to film. I recently got a Minolta 
5400 scanner and have printed about a dozen images on my 1280 with UT 
inks. 

Now previously if anyone has seen threads I've posted before about 
lines running through the prints I've made. I've sent prints to other 
members and one I know of noticed these lines too on the image I 
specified. All the images that I had problems with the lines in the 
prints came from a digital camera (90% on a D100 and a couple from a 
Olympus C4000z). All of the prints thus far that I've printed from 
scanning film show none of these lines at all. But I can go back to a 
D100 image, print and the lines are there.

So as weird as this seems, would there be any logical reason for 
this? I mean aside from the different input devices I've tried 
setting up images the same as best I could for some kind of 
consistancey. The scanner does output at higher dpi, but all I've 
been trying to print thus far is 8x10's. If anyone has any thoughts 
or opinions on this please post I would love to hear them. Thanks!
