Enterprise Browser 2.0 different resolution 1.8

On the new Enterprise Browser 2.0 the resolution is different than the old 1.8 browser.

The font is smaller. How can we change this?

We have a bunch of MC3300 scanners and some of them are running 1.8 and  the others running 2.0.

Can I use 2 different css stylesheets or do we need to update the scanners to look all the same?
