During the PDF export, the program cannot use the font that you selected in the Program Options > Advanced (Tools menu). The export is carried out anyway using the Arial or Helvetica fonts.
Cause
- The font does not contain all the information necessary to be used in a PDf file.
Solutions
- Select another Font under Program Options > General (Tools menu).
- Under Program Options > Advanced - PDF - turn off the option Enable TrueType Fonts.
- Use a pdf virtual printer like 'Microsoft print to PDF'.
- Ignore warnings if the printout is ok.
