Digital BW, The Print

Is it possible to print with MK only on the 1800 without using the QTR
program or other MK inks in the PK and glop positions? I was always
pleased with the BO printing method on my 1280 but it died and will be
replaced  by an 1800. (even with Epson's recent ITC win) 

Had seriously considered the HP9180 but from what I've read the 1800
seems like a better choice.

thanks for any information
