• 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.
• The [data value (k) + control information data value] area of the NV
graphics data domain is used when this function is executed.
• 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.
• 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 I.
• 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.
• The relationship between NV graphics data (raster format) and print
results is shown in the table below.
