What I did, was: I scanned the printed document in black and white using a threshold which resulted in the gray lines scanned as black. I printed out this scanned document; the quality is not perfect but acceptable for my purpose.

Oh. Well, then I'll suggest another method. Import the original pdf in gimp, as a photo. Then adjust the colour curves, or use one of the filters to convert to BW. The quality will be better than print/scan-adjust/print... and maybe easier. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
