Query: Donnot buy this printer

My professor insisted to get this printer for our daily printingjob, and now this machine is annoying to me. It prints Gray color, not black, no matter how hard I have tried the settings. I just need the right color, black, to print my Ph.D. dissertation, that is all. Donnot be alured by the price, the cheap price gives you an output that looks cheap. Donnot buy this one if you need to produce decent document.
