I remember when a copier was a large device, you took a sheet of paper out of a light tight drawer and put it over your original on top, turned on a bright light for multiple seconds, then put that sheet in a liquid in the bottom for some time, then through wringers and heat to dry it out. I was a kid, doing volunteer work in the local alderman's office, just watched, never actually did it.

Corey, I am old mechanical designer. I spent fifteen years on drafting boards, and I happily remember Diazo whiteprinters, often mistakenly called blueprint machines. The output was blue lines on white paper. We drafted and plotted on translucent media, typically drafting vellum or mylar. I don't mind the smell of ammonia. This is now classified as a dangerous material not allowed in offices. The transition in my world is that we have to stop using large drawing formats like E-size (34x44"). This solves drafting board problems, not CAD/printer problems. Offices can print A-size (8.5x11") and B-size (11x17"). We need to switch from 1/8" or 3mm lettering to 2mm and 2.5mm lettering on the A-size and B-size prints, respectively. -- Howard Gibson hgibson@eol.ca http://home.eol.ca/~hgibson
