The Graphic Logo feature allows the storage of a formatted Bitmap file in nonvolatile memory. Up to eight memory sectors, of up
to 64,000 bytes each, are reserved to store a Graphic Logo in the printer. Upon receipt of a Graphic Logo print command, the
Graphic Logo data is sent to the printer. This feature allows printing of a stored graphic image as part of a receipt.
Logo images must be modified and saved to a .prn file prior to logo download.
