||To change this you have to edit the Print Template (File | Edit Print Template).
Highlight the item you want to changet the size of (for example %body%) and then to choose
the font, size and other settings (bold or italic). Save changes.
Make sure to select the %body% tag first (including both % signs), then apply the size and save the
template. You can also use the default template, then edit it again, just in case the template you are
using became corrupt in some way.
(Note: One user reported the settings didn't take until they had shutdown and restarted Poco, this isn't
my experience but if you are experiencing problems this is worth a try).
