X-label cropped when printed to a pdf

Hi,

I have to use big fontsize for a paper that I am writing but when I print my figure to a pdf, the bottom part of the x label is cropped. Please see the figure attached. I would like to keep the print function and pdf format because they give a superior quality. Thanks!
