I Need Help On Epson Printer.

Hello friends. I am new in this forum, and this is the first to post my first post also. Guys, I have a problem with my Epson L3150 printer. The issue is, whenever I am trying to print through my printer, my printer won’t print black and white without color ink. I don't know why this is happening, and how to fix this issue. Anyone can help me with this?

So, guys, I found a solution from found article after searching on Google today. The issue is fixed after applying a process mentioned there. I just enable Grayscale checkbox.
