ppd indesign halftone dot shape

[frederickk]

i'm trying to print my document out at 300dpi 70lpi using lines instead of dots. I know in illustrator CS you can specify what the shape is... dot, ellipse, line, etc... how can you do that in indesign CS? i've created a PPD file in an attempt to tell the printer only to print lines but it's not working. i could post the PPD or if there's an easier or third party solution i would love to know.

thanks.
