There are some good rules of thumb to follow to reduce ribbon waste and increase efficiency, such as - adjusting the printer settings to match the specific ribbon and label material being used. Some thermal transfer ribbons come with an economy mode, this reduces the ribbon usage on parts of a label with no print. Use the correct size ribbon for a given label to minimise waste. It’s also always recommended to regularly maintain the printer to prevent any issues that could lead to ribbon wastage - like misalignments or unnecessary reprints.
