Printing true B&W images on a home printer is very difficult.. in fact, many pro photographers purchase a seperate printer that is used solely for B&W printing (usually one that comes with seperate 50% and 25% grey carts).. When i need to convert to B&W and be spot on in overal tonage, I send them out to WHCC (of course, I send out all my client prints these days.. cost effective as well). My B&W prints come back exactly as I send them out.. as stated before, I just can't say enough good things about them - I just wish I got a kickback from all the customers I've sent their way..
