I can confirm a slight line distance problem when looked at high magnification, but it's also visable at 8 bit per color.

It's a backend issue. The backend must double the x resolution in the 1200/2400 dpi mode. Or better yet, interpolate the missing pixels. As a work aound, you can use gimp or similar programs to double the number of pixels in x direction. Bye, Henning
