Font Name (ASC16)

This is a 16 character ASCII field to which you may assign a font
name. The font name is used in the Typeface List (or Font List
printout), under Name or Typeface (if the printer does not have a
name string assigned to the typeface family code in its font selection
table).
X Resolution (UI)
The X Resolution field is the pixel resolution in the X scan direction at
which the font was designed.
Note This field is not present in the Format 15 Font Header and is not
necessary for TrueType fonts.
