It is not possible to upload a store logo into the read-only memory on the Hobart Quantum scale.
However, your labels can be pre-printed with your store logo and then used on the Quantum.
When you select the option on the scale to have a logo, the scale knows to leave an area free on the printed receipt for the logo.
The scale cannot print the logo itself - the logo must be pre-printed.
The scale can only print a small number of pre-programmed messages, e.g. "Thank You"
