An exact US part number has not yet been confirmed. ### A good shortlist for - Comparing a configurable professional desktop family - Buyers willing to verify a full part number - A supported desktop direct-thermal workflow ### Think twice if you need - Assuming Wi-Fi, Ethernet or a cutter is standard - Treating BLE setup as Bluetooth printing ## The useful specifications. Verified manufacturer specifications | Field | Value | | --- | --- | | Exact model | ZD421d | | Selected US identifier | Not yet verified — check exact listing | | Print method | Direct thermal | | Resolution | 203 dpi · manufacturer specification | | Media / print width | 15–108 mm media / 104 mm print | | Label system | Compatible roll or fanfold direct-thermal media | | Automatic cutter | Not verified for this configuration | | Current price / stock | Confirm at the retailer; no current offer is asserted here. | ## Will it work with your device? **iPhone / iPad** UNCONFIRMED No confirmed direct iPhone print route for the selected USB baseline. **Android** UNCONFIRMED BLE is for setup, not label printing; no confirmed direct mobile print route. **Mac** DOCUMENTED ROUTE Zebra documents a CUPS route; confirm exact model and macOS version. **Windows** DOCUMENTED ROUTE Zebra Windows driver for the selected configuration. A documented route is not a guarantee for every OS version, app or label size. Confirm your exact combination before buying. ### Keep these in view. - Exact US MPN is unverified; manufacturer-information link only. - 300 dpi, network interfaces and cutter are configuration-dependent. - ZD421t, ribbon-cartridge and healthcare models are different variants. ## Where it fits in your workflow. Start from one real label PDF and the device you will actually use. Check the template, print scale, connection route and compatible supplies before judging the printer quote. A marketplace logo does not establish native integration. ## Read next.
