The connection label on a product page tells only part of the story. A printer can include Bluetooth for setup while printing over Wi-Fi. Another can support mobile printing only through a particular app.
The right choice starts with the device and application that will send your shipping labels.
USB: a fixed station with a clear path
USB can suit a dedicated computer on a packing desk. The printer connects directly to that computer, with no wireless network involved in the print path.
Check the driver, operating-system release, connector, and cable. A USB port does not establish that a model supports direct printing from a phone. A shared USB printer may also depend on the connected computer remaining on.
The MUNBYN ITPP941 USB entry here is the wired 203 dpi variant. Its current manufacturer download table lists Windows and Mac drivers plus a Chrome extension. This should not be confused with the 941 Bluetooth or AirPrint models.
Wi-Fi: shared access, with network requirements
Wi-Fi is useful when the printer needs to serve more than one device. Confirm that your network permits those devices to discover and communicate with the printer. Guest networks and isolation settings can interfere.
For Apple devices, AirPrint can provide a supported print route from compatible applications. It is still necessary to set the PDF and paper dimensions correctly. AirPrint support does not mean every app exposes every print setting.
Rollo’s setup guide describes app-based Wi-Fi setup. Bluetooth participates in pairing during setup; that does not make Rollo Wireless a direct Bluetooth label printer. Rollo also documents a 4 × 6 limitation for the standard Android phone flow.
Bluetooth: verify the whole workflow
Look beyond “Bluetooth compatible.” Ask four questions:
- Which operating systems and versions are supported?
- Which application can open and print my shipping-label PDF?
- Does that application support my exact printer variant?
- Are there label-size or print-setting restrictions?
Brother documents Bluetooth on the QL-1110NWB, but explains that its AirPrint connection protocol requires a wired or wireless network, not Bluetooth. Some macOS versions also have specific Bluetooth limitations. A checkbox in a comparison table cannot replace those details.
Tagrivo’s Finder takes a conservative approach: it does not recommend direct Bluetooth shipping-label printing for mobile or Mac combinations we have not sufficiently verified.
A simple decision rule
For one computer that stays at the packing desk, investigate USB first. For a laptop-and-phone workflow or a shared station, investigate Wi-Fi with documented support for your devices. Consider Bluetooth only after confirming the exact OS, app, and model combination.
If your internet connection fails, network printing and buying postage are separate concerns. A functioning local connection does not automatically restore access to a marketplace’s label service.
Compare the connection options or check your setup in the Finder.
