• 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.
• The maximum definition area of this printer is 2M bit (256K
byte). Multiple NV bit images can be defined, but bit images
of which total size (Bit image data + header) exceeds 2M
bit(256K byte) can not be defined.
• The printer state will change to BUSY just before the writing
operation into the non-volatile memory begins. Also,for a
printer that have a dip switch[BUSY], the printer state will
change to BUSY just before the writing operation begins
regardless of the state of the dip switch.
• While this command is being executed, it is not possible to
send ASB status or to detect the printer status even when the
ASB function is selected.
• If this command is sent while a macro is still being defined,
the definition process will be stopped and the execution of
this command will start.
• NV bit images that are defined already are not initialized by
using ESC @ command, or by resetting the printer or turning
the power off.
• The command only executes definition of NV bit image, but
not start printing. The printing of NV bit image will be executed
by FS p.
