403B Great label maker

Great label maker that prints perfect labels each time. We use this with round labels that have always been hard to proces. With the 403B there are no wasted labels and we can print 1 or 50 in seconds.

Works perfectly

Creates shipping labels and apothecary jar labels without a hitch. Easy and simple to use. Excellent quality for the price... don't be tempted by a cheaper product, because they're unreliable and don't last long!

Best Printer For The Money!

I have been using this label printer for a little over a month and I must say I wish I would have purchased it sooner. I tried 2 other brands before this one and the Munbyn WORKS and is super easy to set up and use. Also their customer service is really responsive.

FAQ

What size are standard shipping labels?

The most commonly used shipping label size is 4" × 6" (100 × 150 mm), supported by major marketplaces, carriers, and shipping software worldwide.

RW403B is fully optimized for 4×6 labels, making it the perfect choice for everyday shipping needs.

Do MUNBYN shipping label printers need ink?

No.

All MUNBYN shipping label printers use direct thermal technology, meaning no ink, toner, or ribbons are required.

Simply load labels and start printing, helping businesses reduce long-term operating costs.

Which MUNBYN printer is best for beginners?

For most businesses, we recommend the RW403B.

It offers:

  • Easy Bluetooth & USB setup
  • Reliable daily printing
  • Wide compatibility
  • Affordable ownership costs
  • Three color options

If you're unsure which printer to choose, start with RW403B.

Which printer is better for growing eCommerce stores?

RW403B is designed specifically for growing businesses.

Whether you're shipping 10 orders a week or hundreds a day, it provides the reliability and simplicity needed to scale your operations.

For businesses requiring premium branding labels or smaller detailed labels, a 300 DPI model may be considered later, such as RW941BP.

Which printer should I choose if I need WiFi or AirPrint?

If WiFi or Apple AirPrint connectivity is essential, we recommend:

However, for most sellers, RW403B's Bluetooth connection already provides a fast and convenient wireless printing experience.

Can I print product labels with a shipping label printer?

Yes.

RW403B supports much more than shipping labels, including:

  • Product labels
  • Barcode labels
  • Inventory labels
  • Address labels
  • Thank-you stickers
  • QR code labels

It can support both shipping operations and brand packaging workflows.

What labels should I buy with my printer?

For the best experience, we recommend pairing RW403B with:

  • 4×6 Shipping Labels
  • Round Branding Labels
  • Thank You Stickers
  • Label Holder
  • Shipping Scale

You can also explore our curated RW403B Business Kits for different selling scenarios.

Should I choose 203DPI or 300DPI for shipping labels?

For most businesses, 203 DPI is more than enough for shipping labels, barcodes, and everyday operations.

Choose 300 DPI only if you need:

  • Extremely small text
  • Premium product labels
  • Fine logos and graphics
  • High-density barcode printing

For standard shipping and daily business use, RW403B's 203 DPI provides excellent performance and value.
