When I was in school a girl knocked her lamp over and managed to start a fire on her whole worktable that went into the liter bottle of denatured alcohol. Jeez. Some people just shouldn't be given fire. We had a rule that you weren't supposed to scream when shit like that happens because then everyone else panics and knocks there lamps over and catches their hair on fire.
Try scanning your maps next time and printing with a nice color printer.
