Increase, Decrease, and Print button

I'm using bootstrap and by default the font is 1rem when I click the print button it does not take the default size of the document it takes a very small font to mount the increase and decrease font button I'm using a jquery Jfontsize will have something to hinder it from getting the right font size.

Can anyone help me?

     $('a, p, h1, h2, h3, h4, h5, h6, img, figcaption, footer, span, li, ul, ol, td, th, tr').jfontsize({
        btnMinusClasseId: '#jfontsize-m2', 
        btnDefaultClasseId: '#jfontsize-d2', 
        btnPlusClasseId: '#jfontsize-p2', 
        btnMinusMaxHits: 1,
        btnPlusMaxHits: 3, 
        sizeChange: 5
    });

jquery.jfontsize-2.js
