Since installing my PSC 2110 on a new Acer computer with Vista home premium it will not allow me to specify printing from the black cartridge only - which I could previously do on my old computer with XP.
I had the same problem with my HP printer when I upgraded my OS from 98SE to XP. I tried to update the drivers from the HP website but had no luck. Have a try and see if you have more luck than I did, or search the internet for updated drivers.
