I need to change to size of the print

I need to change the size of my print on my printer. It is too small. I can hardly read what comes out of the printer.. Is there a way to make the letters a little bit bigger? Can I change the size from my computer or from the printer intself. Please let me know.-----------------need to know-----------p.s I have a Brother printer MFC-440CN and a desk top Dell. The computer is 2 or 3 years old and the printer is not even a year old.

text is too small to read after printing
