Three options for Font Type are provided,
AFP Raster Fonts
AFP Outline Fonts
We recommend TrueType fonts among the three options so as to get the best output fidelity. Some AFP enabled printers require that the printers are configured to accept TrueType fonts.
AFP Raster Fonts are fonts whose graphic character shapes are defined by small raster patterns.
AFP Outline Fonts are fonts fully compliant to the Adobe Type 1 Font standards, and graphic character shapes are defined by mathematical equations rather than by raster patterns.
Please check with your printer manufacturer to see if your AFP enabled printer supports TrueType fonts, Raster Fonts, and Outline Fonts.
