These character tables are selected using the printer's Default
Setting mode or by using software commands.
All tables except the italic are the same as the PC437 table for
hex codes 00 through 7F, so only the PC437 table is shown
completely. The rest of the tables show only the characters for
hex codes 80 through FF.
