Storing media safely and managing your supplies will keep your media ready to use.
Store media in a clean, dry, cool, dark area. Direct thermal media is chemically treated to be heat sensitive. Direct sunlight or heat sources may expose the media.
Do not store media with chemicals or cleaning products.
Leave media in its protective packaging until it is going to be put in the printer.
Many media types and label adhesives have a shelf life or expiration date. Always use the oldest, viable (non-expired) media first.
