Title: Seeking CUPS filter to convert gray to black
Tags: colors;printing;cups;filter
Question: I get a lot of documents containing color for no good reason.  I want them printed in solid black with no gray.  I see some questions about this here along with some printer-specific suggestions, but no solutions.  Rather than attack the problem from the printer end, would someone please suggest a CUPS filter that converts anything that's not blank into stark black?
My primary printers are black-and-white lasers.
