Enlarge print size on HP laptop computer?

I have an HP laptop computer and the print size is way too small. I normally print graphics using microsoft excel. How can I enlarge the print size so it fills the entire sheet?

You can't increase the font size with your printer. It does not have that option. You need to increase the size from source of which you are getting the data from.

Otherwise just check the printing options. You might find something there.
