Re Gerardo's black diagramI hate to rain on your parade, but this probably wouldn't work very well. Unless you use extremely expensive ink and paper, the black is quite likely to bleed,making the diagram difficult to read. It would also use up a lot of ink. Joe Power
Laser printers work beautifully - no bleed - toner lasts "forever" - and today they are very low cost. Personally, I print heavy graphics - Konica Minolta makes an excellent machine - since 1998 I have been exceptionally pleased.
