Genuine Bluetooth Module for Label Printers

This genuine Brother B55L477-1 Bluetooth module adds wireless connectivity to compatible label printers. It supports the RJ-4030, QL-810W and QL-810WNB models directly. The part enables cable-free printing from mobile devices or computers. It is a factory replacement component for specific Brother hardware.

Thermals Noise and Power Draw

The module draws minimal power from the printer's internal supply during operation. It produces no audible noise because it contains no moving parts or cooling fans. Heat output is negligible and requires no additional ventilation considerations. Normal use has no measurable impact on the printer's thermal profile.

Build Quality and Daily Implications

Each unit has been inspected, cleaned and quality assured to meet manufacturer specifications before shipping. The module installs internally to maintain the printer's original exterior profile. Cosmetic marks or scratches may exist on non-critical surfaces per the supplier disclaimer. Wireless pairing replaces wired connections for daily label printing tasks.

Questions about this item

How do I install the B55L477-1 Bluetooth module into my RJ-4030 printer, and what step is commonly missed?

Power off the RJ-4030, open the side cover, slide the B55L477-1 module into the internal slot until it clicks, then close the cover; the step often missed is forgetting to power-cycle the printer so the firmware recognises the new module.

What maintenance or replacement will the BRBT2G4RJ3 module need over time?

The module itself has no user-serviceable parts; keep the printer’s exterior vents clear of dust and ensure the label-roll compartment stays clean so heat does not build up around the Bluetooth board.

What is the first limit I will hit when printing large batches over Bluetooth on the QL-810W?

Sustained high-volume printing will reach the QL-810W’s internal buffer and thermal print-head duty cycle before the Bluetooth link becomes the bottleneck.
