A5 Printing

A5 prints except for one issue I wish I could solve!
Is it possible to increase my font size?
When I print on A4 everything is fine.
But when I go A5, everything seems really small.
Is there a way I could increase the font size?

However you are printing to A5 paper, this is not a built-in capability of Manager, which handles only USLetter and A4 natively. Font size changes require custom themes. You are responsible for their creation and performance yourself.

Is there any coding or something else so that we can create custom theme and change font size of invoice accordingly in A5 paper
