1-1/2 to 2x the halftone screen gives about as good a resolution as you are going to get. Some on this list have argued that inkjet printers don't use a halftone screen. That is wrong they use a software generated halftone screen. My Epson 820 uses 144 lpi. Interestingly, when I up graded the drivers, the new ones seem to indicate you can change that to higher numbers though I have not tried playing with that setting. Anyway, with a 144 screen there is no reason to go higher than 200dpi or so.
