If you convert your OOo generated PDFs to PostScript using pdftops (from the 
xpdf suite) and then prepend the attached forceblack.ps to the resulting 
PostScript file, RGB colors where R==G==B will be printed as pure black 
(replaced with the appropriate gray value).

Note that this trick won't work with PDF input or PostScript produced using 
Ghostscript's ps2write device.
