If you go to the printer properties, there should be an option somewhere (not sure which tab) where you can select grey scale. Either that or manually select grey scale in the program that you print from.
tks. for the reply.
the answer given, i hope to get a black&white print when all the four cartridges are ok condition.. My question is when the color cartridges are to be replaced(when the ink over), is it possible to print black&white. there will be alarm(visual) to indicate the ink exhausted. In that condition it is not possbile to take print.
