Find the Print Command
First, launch the Firefox internet tool.
In the upper-right corner, selectMenu(three horizontal lines).
When the pop-out menu appears, choose thePrintoption.

IfPortrait(the default option) is selected, the page prints in the standard vertical format.
Here you could modify the dimensions of a page for printing purposes.
By default, theShrink To Fitoption is selected.

This is by design since most people want to print only text and foreground images.
