B-2 Internal Symbol Set Charts ENWW
The gray shaded areas in these tables denote printer control code
areas. Math composite characters are shown with light-colored
shades, and line-draw composite characters are shown with
dark-colored shades. Composite characters are made by combining
individual character elements into a large character.
The International Organization for Standardization (ISO) symbol sets
and the HP German and HP Spanish symbol sets are represented by
a character substitution table (see page B-19). The final table, the
Roman-8 Character Conversion table identifies the hexadecimal,
decimal, and octal codes for the Roman-8 symbol set.
Note To identify the symbol sets that are supported by a printer, refer to
Chapter 3, Internal Typefaces/Fonts and Symbol Sets,” in this
