Could you please share your workflow steps?
Do you mean to increase the font of photo info in Print module in Lightroom or some other module?
Which version of Lightroom do you have?
Do you mean change the font itself, or change the font size?
I'm using Lightroom 5 when I go to print I can't change the font that prints I can only change the size of the font. It looks like an arial default font. Hope that helps.
