I can't imagine that Adobe really forgot this but maybe they did: There is no check box to print color-pdf files in monochrome. Result is a very fuzzy printout with some information in certain colors completely missing. For CAD drawings that's decidedly uncool.
A web search brought up oodles of routines to strip color out of pdf. But in this day and age one has to be careful with downloads. Anyone know how to print in monochrome, or which converter program is safe?
PDFCreator has a monochrome switch but when trying to print to that from within Acrobat Reader it crashes.
