Epson FX Emulation9–54
Reassign Graphics Mode
ASCII Code ESC ? s m
HEX Code 1B 3F s m
Purpose Changes one graphics mode to another.
Comment s is character K, L, Y, or Z, which is changed to mode m (0–7) from
Table 9–3 (page 9–53). Thereafter, sending data to the bit image
command makes the data print according to the graphics mode you
select with m.
Select 9–Pin Graphics Mode
ASCII Code ESC ^ m n1 n2 d1 ... dk
HEX Code 1B 5E m n1 n2 d1 ... dk
Purpose Turns on 9–pin bit image graphics mode.
Comment m defines the plot density as shown in Table 9–4, on page 9–53.
n1 + (n2 x 256) = The total number of columns.
This mode requires two bytes of graphic data for every column of
print. Each column is sent as a pair: d1, d3, ... d(k–1) set the top 8
bits of a normal dot column, just like ESC K; d2, d4, ... dk set the
ninth dot in the column (the most significant bit) just below the
bottom–most dot of columns d1, d3, ... d(k–1).
