[Function]	Defining the download NV bit image

[Outline]	This command defines the specified NV bit image.
	• “n” denotes the number of bit images to be defined.
	• xL and xH denote the horizontal size of one NV bit image as (xL + xH ⋅ 256) ⋅ 8 dots.
	• yL and yH denote the vertical size of one NV bit image as (yL + yH ⋅ 256 ) ⋅ 8 dots.
[Caution]	• Because all the NV bit images previously defined by this command are deleted, it is

not possible to redefine any one of the previously defined multiple data. All the data must be resent.

• From the execution of this command until the completion of the hardware reset, any mechanical operation such as opening the cover, initializing the printer head position, or using the paper-feed switch etc.

• The NV bit image refers to a bit image that is defined by the FS q command in the non-volatile memory and printed by the FS p command.

• When the STANDARD MODE is selected, this command is only valid when it is written at the head of a line.

• This command is invalid when PAGE MODE is selected.

• This command becomes valid after the 7 bytes of <FS q n xL xH yL yH> are processed as normal values.

• When data which exceeds the remaining capacity of the defined area is specified by xL, xH, yL, yH, outside-defined-area arguments will be processed.

• When outside-defined-area arguments are processed for the first bit image data group, this command becomes invalid.

• If outside-defined-area arguments are processed for the second or subsequent NV bit image data groups, the processing of this command is suspended, and a writing process into the non-volatile memory starts. At this time, the NV bit image being defined becomes invalid (Undefined), but the preceding NV bit images are valid.

• “d” denotes the definition data. Bits which correspond to dots to be printed are represented as “1”, and those not to be printed as “0”.

• The definition will start from NV bit image number 01H and n-number bit images will be defined in ascending order. Therefore, the first data group [xL xH yL yH d1… dk] becomes NV bit image number 01H, and the last data group [xL xH yL yH d1… dk] becomes NV bit image number 0nH. These numbers of NV bit images coincide with those specified with FS p.

• The definition data of one NV bit image consists of [xL xH yL yH d1… dk]. Therefore, when only one NV bit image is defined, n = 1; the data group [xL xH yL yH d1… dk] is manipulated once, and ([Data: (xL + xH ⋅ 256) ⋅ ( yL + yH ⋅ 256 ) ⋅ 8 ] + [Header: 4]) bytes of non-volatile memory is used to store it.
