Digital BW, The Print

I've just joined this forum and have already found the posts to be
informative and interesting.  I also just recently read Clayton Jones'
articles on black only printing.  I'm getting good results so far with my
new Epson 2200 using his method, using the Epson Matte Black cartridge and
Enhanced Matte paper.  I'm interested in trying the Eboni black ink
cartridge mentioned by him and others, but I couldn't find the ARC TO348-K
cartridge he refers to on the inksupply.com website.   The ones they do have
seem to be for the Mac version only.  Am I missing something, or has the
number changed?

What do I need to use the Eboni ink in place of the Epson Matte black ink in
my 2200?  I'm using a PC, with XP.

Thanks for any info, and I'm looking forward to getting to know you all
here.
