Description
GS - defines a bit-image for storage in the nonvolatile memory pool. The
printer maintains an area of memory specifically designated for multiple
bit-image storage. This area can contain as many bit-images as its size
permits. (A printout of the amount of nonvolatile memory remaining can
be obtained by performing a printer self-test.) Each image is uniquely
identified by the name given to it by the <
name
> parameter.
The name of the bit-image can be from one to 15 bytes long and contain
any alphanumeric characters as well as the space. The format of the bit-
image is identical to that defined by the GS * command.
The GS - command must be entered in standard mode only at the
beginning of a print line. If this command is entered in page mode, it will
be ignored. If the size of the image is larger than the space remaining in
the nonvolatile buffer, the image will not be saved. When the last byte of
bit-image data is received and there is ample space in the nonvolatile
buffer for the bit-image, the bit image will be saved. While the save is in
process, the printer will go off-line and will not respond to or save any data
it receives. When the save is complete, the printer will return on-line.
Please be sure to adhere to flow-control provided by the communications
interface.
