When printing estimates, invoices, etc., some text can be missing from the printed document although it appears on the screen.
This usually occurs when the font on a template has been changed to use an Open Font Format. QuickBooks is designed to only use True Type Font format.
In order to use your special font within Quickbooks, it must first be converted to a True Type Font (.ttf) and installed to Windows. Converting to a .ttf font requires a font converter and many free ones can be found on the web, such as freefontconverter.com.
