Atom label fonts are too small when printing from ChemFinder.
The structure is scaled to fit into the box you have created to display it. To increase the size of the structure, you must increase the size of the box used to display it.
If fonts get scaled too small when printing, you could create a separate form for printing, and increase the font size on the structures. The screen display won't be so great, but it will print ok. You can adjust the font size using Box Properties. In Layout Mode, right click on the structure box and choose Properties. In the Box tab there is a "Font..." button. Click on this to adjust the size of the font for the structure. Try adjusting the size as well as the font --- some fonts are scalable, some are not.
