ESC 7 Cancel “ESC 6” commands
Format:
ASCII: ESC 7
decimal: 27 55
hexadecimal: 1B 37
Comment:
This command, whose response is opposite to ESC 6, allows for using characters from
128 to 159 as control characters.
4.4 GRAPHIC CAPABILITIES
The graphics pattern is printed immediately; if the dots are more than the possible
dotline, the printer begins an other line.
If you do not put CR at the end, everything that follows the graphics printed, is set
sideways of it. The arrival of a graphics command causes the printing of the line buffer
and sideways follows the graphics.
4.4.1 Graphics control characters
ESC * m n1 n2 data General bit image command
format:
ASCII: ESC * m n1 n2 … graphic data …
decimal: 27 42 m n1 n2 … graphic data …
hexadecimal: 1B 2A m n1 n2 … graphic data …
Comment:
This command selects one of a number of bit image data modes according to the value
of m in the following table 10.
Table 10
m MODE dots/inch dots/mm
0 single density 60 2.36
1 low speed/double density 120 4.72
2 high speed/double density 120 4.72
3 quadruple density 240 9.45
n1 and n2 determine the number of “n” of a bit image data, which follw the command.
Their values are calculated as follows:
n1 = d MOD 256
n2 = INT (d/256)
where d is the number of data bytes to be sent.
Note:
MOD is the modulus 256 operator (remainder of the division of d by 256); INT is
the operator that yields the integer part of (d/256).
