Zebra Media Core Adapters for 1.5", 2" and 3" Label Roll Cores · Set of 2 Each · for ZD420, ZD421, ZD620 and ZD621 Printers

The Zebra P1080383-022 is a set of media core adapters that lets Zebra’s 4-inch desktop label printers hold label rolls wound on 1.5-inch, 2-inch and 3-inch cores. Zebra’s Desktop Printers Accessories Guide describes it as "Media Core Adapters for 1.5", 2" and 3" Diameter Cores (set of 2 each)" under Media Handling Options.

It is for users who buy labels from different converters — or who move from small retail rolls to larger industrial-style rolls — and need the printer’s roll holders to grip a different core size securely.

• Media core adapters for 1.5", 2" and 3" cores — 2 of each size (part P1080383-022)
• No labels or roll holders are included — the adapters fit the printer’s existing roll holders

• Buy labels on whichever core size your supplier offers and still load them correctly
• Larger 3" cores usually mean longer rolls and fewer roll changes
• Keeps the roll centred, which helps tracking and reduces label skew

• Printers not on Zebra’s list (for example ZD411, ZD611, GK/GX or ZT industrial models)
• Rolls with outside diameter larger than the printer can physically hold — the adapters change the core size, not the printer’s maximum roll size
• Ribbon cores — these are for label (media) rolls only
