Best Answer -
That entirely depends on what you are printing. A printerwill only produce what it is given.
If you are printing your own document then you change the font in the documentbefore printing or select the font before you start.
However I suspect the reason you are asking this is because you are printing apdf document from the internet. In which case the font is fixed.
If so, then you will have to copy and paste the document in to a word processorlike Word, highlight it all and the increase the font. You will then have toreformat the whole document as the increased font will throw the orginalformatting all out of line.
When you have straightened it all up then print it off.
ALTERNATIVELY, if you are printing on ordinary web page then you need to follow the below instruction
Go to theweb
page that you want to print and right-click it. Click "PrintPreview." If you want to print part of the page, highlight the contentthat you want to print and right-click the selection. Click "PrintPreview."
Click the "Page Setup" icon located onthe top of the Print Preview window to launch the Page Setup dialog box. Click"Change Font."
Select the font you want to use in the"Size" window. If you want to change the font type, make yourselection in the "Font" window. Click "OK" to save thechanges and click "OK" again.
Turn on your printer if it is not on. Click the"Print" icon on the Print Preview window to print your web page.
