QTR-Quadtone RIP

I've been in the printing industry a long time, but have never printed black and white inkjets....the only BW i've done was traditional(darkroom), and though quite familiar with color printing in the digital realm, I have only tried BW a few times on my Epson 1800 with fairly poor results. The folks I know who print BW usually print to dedicated BW printers, or at least have printers with the 3K option.....

I read on a forum that the Quadtone Rip is great, but just glancing quickly at this forum, I'm gathering that you would need to put a whole different ink set in your 1800 to print BW...yes? no? I have the standard inks in it now, so there is just a photo black and a matte black in it, then color inks.....The person who posted says it works with all inks, but I'm feeling skeptical and would love a simple explanation/clarification before I get knee deep in something that won't even work with my equipment....thanks
