The invariable result is ugly square dots at about 45 lpi regardless of my settings. I suspect that the problem is with the hp printer, not Scribus. Ghostscript will do what you want, however. Set DITHERPPI to the desired screen ruling. You'll get well-defined round dots and smooth gradients that print beautifully. I make a lot of laser plates for a local print shop on a Laserjet 5000. The optimum screen ruling is about 95-105 lpi. Finer rulings (up to 120 lpi) are possible, but above 105 lpi other limitations of the printer kick in.
