Description
GS 6 saves the current character set created by the “ESC &” command to
the nonvolatile memory pool. If no character set has been defined, this
command will be ignored. When saving an image, the printer will go off-
line and will return on-line when completed. Please be sure to adhere to
flow-control provided by the communication interface.
Once a character set has been saved to the nonvolatile memory pool it is
“read-only”. Any attempt to redefine a character when this set is selected
will cause a new character set to be defined in RAM according to the “ESC
&” command.
