FAQs

Please read our FAQs page to find out more.

What is the MUNBYN RW941B designed for?

The MUNBYN RW941B is a 203 DPI thermal label printer for daily shipping, barcode, address, inventory, and product labeling. It is designed for online sellers, home offices, retail operations, and warehouses that need fast 4 x 6 label printing without ink or toner.

How does the MUNBYN RW941B connect to phones and computers?

The RW941B uses Bluetooth with iOS and Android phones or tablets through the MUNBYN Print app. Windows, macOS, Linux, and Chromebook computers connect by USB. Choose the connection intended for your device and confirm the label dimensions before printing.

Which marketplaces and carriers are compatible with the RW941B?

The RW941B can print labels from Shopify, Etsy, eBay, Amazon, Poshmark, Royal Mail, FedEx, ShipStation, ShippingEasy, and other shipping services. Download or open the label from the platform, select the RW941B, and keep the document at its intended size for reliable barcode scanning.

What label widths does the MUNBYN RW941B support?

The RW941B supports direct thermal labels from 40 to 110 mm wide, or approximately 1.57 to 4.3 inches. It can handle standard 4 x 6 shipping labels as well as narrower barcode, address, product, and organization labels. Recalibrate after switching to a different size.

Does the RW941B need ink, toner, or ribbons?

No. The RW941B uses direct thermal technology, so the only regular printing consumable is compatible direct thermal label media. Protect unused labels from heat, moisture, and direct sunlight because these conditions can affect the thermal coating.

How fast and clear is the MUNBYN RW941B?

The RW941B prints at 203 DPI with a listed speed of up to 150 mm/s. This resolution is suitable for standard shipping text, addresses, and barcodes. Label quality, print density, connection type, and the complexity of the document can affect actual output.

How does automatic label identification work on the RW941B?

Automatic label identification helps the RW941B detect and calibrate the loaded media so each print begins in the correct position. Load the labels straight, adjust the guides, and run calibration after changing sizes. The document must still use the correct width, height, orientation, and scale.

What should I check if the RW941B prints blank or misaligned labels?

Make sure the thermal side of the label faces the print head, then reload the media straight and recalibrate. Verify the document size and disable scaling that changes the layout. A test print can confirm alignment before a batch. The RW941B includes a two-year warranty and technical support.
