That bug has been opened on https://launchpad.net/distros/ubuntu/+source/gedit/+bug/35679 "When you are viewing a print preview, you often want to adjust some of the page settings. After adjusting these settings, you expect to see them in effect in your preview, but they do not. To reproduce: Open up a file in gedit Load print priview Change font to 20 in page settings Look at preview, it's at the original font. It's minorly annoying to close out of preview and open it up again to view changes to your page settings."
I can confirm that the problem exists for myself also, a quick solution I guess would be to disable changes or to refresh the preview (if it's a simple task).
refreshing the preview in real time is not really possible since the text has to be repaginated. Beside the new GtkPrint code doesn't allow to tweak print settings while showing the preview. Marking as WONTFIX
