Split Print Job to Color and B&W?

cheros writes "I work in an office which has various printers, and printing documents with a few color diagrams in is actually a pain. Due to the high cost of the color prints the preference is to use B&W, and print the color pages separately (with obviously an finishing stage to collate and merge the two). Is there a print filter that would automatically split the PostScript print job into a feed for two different queues? (and yes, we use B&W drawings where possible ;-)."

one trick that could work would be to add some functions in the postscript header. Basically, overload all color operators so that if they are called, they flag the current page (or better they check if the color or image they are passed is really color). If the flag is present ignore the next showpage operator and flush the graphic state.

Oooh, I like this one. Combine this with what I'd described earlier -- have the input filter add this to the heder, with "ignore==color" and send to the B&W printer, then again with "ignore==b&w" and send to the color printer.

Again, though, I think you're going to depend on having a geeky-geek there to write it for you (and more importantly, fix it when it runs across really weird data that doesn't quite fit right...)
