Not black and white printing is a missing color!

Compared to my old Lexmark printer is disappointing that more than one: passable finish, any print quality. Good is not good but I could have done with.
But especially Epson cartridges management policy that I did not know is purely outrageous: you want to print in black and white? Your black cartridge is full, your text is black on white?
Ah but my good sir your magenta cartridge is empty: it's nerd but printing is not possible.
It was nice change each menu (printing grayscale ...), begging the printer to only use the BLACK because it takes print contains only BLACK and not nothing works must go to the cashier to buy a cartridge that you did not necessarily need the day you need to print. Even the black and white photocopy is impossible too ...
Epson short it's over for me ...
