■
This function is incompatible with macros, so make sure to avoid including it when defining macros.
■
In cases where there is insufficient capacity available for storing downloaded graphics data, this function
cannot be used. Use Function 52 to confirm the available capacity in the downloaded graphics data area.
■
One option is to delete items of downloaded graphics data that were previously defined to the same key
code.
■
The data for byte
k
of
d1 ... dk
is processed as a single item of defined downloaded graphics data. The
defined data (
d
) specifies “1” for bits corresponding to dots that will be printed and “0” for bits
corresponding to dots that will not be printed.
■
Downloaded graphics data is defined using the dot density set by Function 49.
■
Specify single data groups [
c d1 ... dk
] when monochrome is selected (
b
= 1) as the color.
■
Specify b number of data groups [ c d1 ... dk ] when multiple colors are selected ( b
≠
1). It is also
important to specify different colors in units of data groups when specifying color ( c ).
■
Downloaded graphics data is printed using Function 85.
■
Note that it is not possible to create definitions for both downloaded graphics data (this command) and
downloaded bit image data (
GS
✻
). Downloaded bit image data definitions are deleted when this
command is used.
■
For some models, downloaded graphics (this command) and user-defined characters ( ESC & ) cannot be
defined simultaneously.
• User-defined characters defined are deleted by using this command.
• Downloaded graphics data are deleted by ESC & .
■
The relationship between downloaded graphics data (raster format) and print results is shown in the table
below.
