Technical Manual PRINTER CHD6800

* This command may interfere with ordinary text printing command if sent while text line has
not been printed.
* This command is effective when 7 bytes <FS~yH> is processed as normal value.
* If image dimensions exceed 384x384 pixels, the command and data is ignored.
* d is the defined data. A 1 bit specifies a dot to be printed and a 0 bit specifies a dot not to
be printed.
* This command can define several NV bit images.
*Once a NV bit image is defined, it is not cleared by executing ESC @, reset, power off.
*This command executes only definition of a NV bit image and does not perform printing.
Printing of NV bit image is executed by FS p.
*Frequent command execution may cause damage the NV memory. Thus, it is strongly
recommended to write the NV memory 10 times a day.
* This command should not contain DLE EOT (Real time status) byte sequences.
* This command can contain DLE EOT (Real time status) byte sequence starting with
v5.5.0 (6800W) and higher versions.
* Sending this command will discard user defined characters (ESC &), print bitmap block
(GS q) and print raster bit image (GS v 0).
