How do I get rid of brother printer not printing error?

From the last three or four weeks, my brother printer is showing the incapability of printing. I am trying to apply the printing command to my printer, but it is refusing for printing. I am facing the technical error such as brother printer not printing, so I don’t have ideas to sort out this technical glitch. I try to identify the actual causes of it, but I don’t get the real causes. I am facing a lot of trouble to identify the causes and applying the right skills for resolving it. Nothing is going to right. Anyone can help me.
