Hi! How do we add a logo and design? Or is this just an order for the paper? Than we add and print ourselves?

The OL823 is available on our website blank, however if you'd like custom printing please reach out to our Customer Support at 888-575-2235. Whether you want to design and print yourself or design a label and submit it for custom printing, you can use our free Maestro Label Designer at the link below. https://www.onlinelabels.com/maestro-label-designer
