    Some one in the group did the maths on the printer head holes & 
pointed out if I remember that if you wanted to do good plots of tracks 
between IC Pads you needed to us a printer of around 1440dpi (its 
something to do with the number of holes per color) & the lower 
resolution printers have fewer holes so less achievable resolution when 
printing in on copper using one ink (yellow magenta works best I've 
found). Anyway its in the Archives I found it enjoy
