Reinstalling the CAESAR II application will probably have no effect.

I am not familiar with Richo's printers or their drivers. Check if there are any default font/size settings available. Check if there are any newer drivers available (from the manufacturer site).

Did you try the suggestion to modify Custom Reports for fonts/sizes (as discussed in your previous message) [http://www.coade.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=10734&page=1#Post10734]?
