[Description]
1.
The "ESC [F1]+[01]+[02]+[02]+[n]" command specifies the dot history factor, which is defined as a
percentage of the total burn time.
2.
Dot history is useful for preventing the over-heating of large, dark areas that is caused by
individual heating elements in the thermal printhead building up residual heat due to repeated,
sequential activation, (also called "burns").
3.
If dot history is enabled, then each dot line is burned in two phases: a main-burn phase and a
post-burn phase. During the main-burn phase all required dots are burned. During the post-burn
phase, only those required dots that were not burned in printing the previous dot line are burned.
(The term "required dots" refers to the individual dots that must be burned to create the current
dot line.)
4.
The duration of both the main-burn phase and the post-burn phase are defined by the dot history
factor, which specifies the percentage of the total burn time that is used for post-burning.
5.
The default dot history post-burn factor is stored in flash memory, and its value can be 0 to 99%.
Dot history is enabled if the dot history post-burn factor is not equal to zero, and is disabled if the
dot history post-burn factor equals zero.
6.
Parameter [n] defines the dot history post-burn factor in percentage of the total burn time. The
range of parameter [n] is [0]
10
[0]

[1]
to [99]
specifies a current dot history pre-burn factor that is 1 to 99 percent of
the total burn time
7.
The printer status information that is printed after paper insertion also contains information on the
dot history pre-burn factor, providing that dot history is enabled.
8.
The print speed must be limited to a maximum of 130 mm/s if dot history is enabled and limited to
a maximum of 100 mm/s if multi-strobe burning is also enabled. (Note that the eXtendo
automatically limits the print speed if this feature is enabled).
