Digital BW, The Print

In addition to good reports from IP users, I think there may be a few options if you want to stick with OEM color ink. I may need to be corrected, but my small knowledge of QTR and IJC make me think IP's use of K, ltK, ltC, and ltM for mono prints could be duplicated with either of those two less expensive drivers. QTR is free untill Roy wonders where the last year went.
Might be worth checking out if you are on the Mac.
