Canon printer only prints in very small letters....

Question

I have a Canon Pixma IP1600 and everytime I want to print
osomething it comes out very small that I can hardly read with a magnifyer. Can you please help me? I just don't know what
to do. I cannot keep them because I can't read them. I rely
on printing !
Thank You,
