Published specification
What is true of this model and changes how you fix it
- Official specificationsUp to 110 standard address labels per minute at 300dpi (300x600dpi max). Bluetooth, Ethernet, and Wi-Fi (802.11b/g/n) plus a USB Host port for peripherals like a scanner. Automatic cutter after each label or for custom sizes. Backlit monochrome LCD for standalone use.
- Type — thermal LABEL printer (no ink, no toner)This is a LABEL printer, not a document printer — it prints labels using DIRECT THERMAL technology (heat on special thermal label rolls), so it has NO ink and NO toner. Ink/toner, printhead-clog, color and scan/copy symptoms do NOT apply; it only prints labels from DK label rolls.
- Thermal labels & fadingIt uses Brother DK label rolls; the printer detects genuine rolls. Direct-thermal labels can fade over time or with heat/sunlight — that is the media, not a fault. A blank print usually means the label roll is loaded wrong-side or is not genuine/detected.
- ConnectivityWi-Fi/Ethernet/Bluetooth/USB; used with P-touch Editor/label software. 'Offline' is usually a network/queue issue.
- CutterRated for up to 300,000 cuts on die-cut labels and 150,000 on continuous labels.
- ConnectivityBluetooth 2.1+EDR, wireless 802.11 b/g/n, Ethernet, Wi-Fi Direct and a USB 2.0 host, with the iPrint&Label app and AirPrint.
- Software and sizeP-touch Editor for Windows and Mac, a backlit monochrome LCD and 7.8 MB of memory, at 5.0 x 9.2 x 5.7 in and 2.5 lb.

Questions that only have an answer for the Brother QL-820NWB label printer
My Brother QL-820NWB prints blank labels.+
Blank labels on a direct-thermal printer usually mean the label roll is loaded the wrong way (the printable/thermal side must face the print head) or the roll is not a genuine Brother DK roll the printer can detect. Reload a genuine DK roll the correct way and make sure it is seated so the sensor reads it. There is no ink or toner to check — it prints by heating thermal labels — so it never clogs, but it only works with the right thermal media loaded correctly.
