Digital BW, The Print

Hi Steve!

I have the same problem as you with lines when printing 100% black, 
but I use a PC.
I also tried to print a colour document with the Epson driver and the 
lines are not there.
Have you found a solution for this problem?
How much noise did you ad to your black to get rid of the lines?
