•
k
indicates the number of the definition data.
k
is an explanation parameter; therefore it does not
need to be transmitted.
■In cases where the specified key code already exists in memory, it will be necessary to overwrite the data.
[Notes] ■NV graphics indicate image data groups defined in the printer’s internal non-volatile memory. Data
definitions for NV graphics data created using this command are valid until redefined by this function or
<Function 68>.
■The functions used to define NV graphics data are this function and Function 68. Even with printer models
that support both, it is recommended that only one of the functions be used for data definition tasks.
• The two functions differ only in that one function (this function) defines data in raster format, while
the other (Function 68) defines data in column format. The domains and control information are
identical.
• In cases where the key code specified by this function coincides with a key code being used by
Function 68, a new data definition is created.
■Use this function at the beginning of the line when the standard mode is selected.
■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 NV graphics data, this function cannot be
used. Use Function 51 to confirm the available capacity in the NV graphics data area.
■One option is to delete items of NV 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 NV 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.
■NV 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
).
■NV graphics data is printed using Function 69.
■Note that it is not possible to create definitions for both NV graphics data (this command) and NV bit
image data (FS q). NV bit image data definitions are deleted when this command is used.
