    I use a Canon MG 6821 injet all in one printer and believed I was conserving the color inks by printing only in the business letter preference setting with grayscale, duplex selected. However, my color inks are consumed very rapidly especially the magenta? Wondering why this is happening - am I incorrect that colors are not used when grayscale print is selected? Any suggestions or insights would be appreciated.
