    Replaced my Munbyn 941 thermal label printer after the calibration stopped working. Been using the RW403B for almost a month and I really like it. Overall, a much more efficient printer (less wasted label paper) and love the remote printing (fewer cables!).

    Pros
    * It only uses 1 label per print — no more wasted blank labels cycling through before or after printing
    * Bluetooth connection. Doesn’t use up a USB port space. One less cable on my desk.
    * Can print labels from my phone when I’m not at my desk
    * Small size. Takes up less space than the 941 model (see comparison photo)
    * Better price. Cheaper than my older model.

    Cons
    * Was a bit challenging to set up. The link to the driver on the manual went to a YouTube video. They since corrected the link, but it took my a long time to find this driver on my own!
    * Had trouble connecting to Bluetooth on my Mac. It kept showing it was connected but when I went to print, it would suddenly disconnect. I re-installed the printer and restarted my Mac a couple times. It mysteriously works now as a remote printer, even though it doesn’t show up as “Connected” on my Bluetooth dropdown menu on my Mac. Weird.
    * Printed label is slightly lighter shade of black vs my 941 model. Still totally legible, just not as high contrast / rich black.

    It was easy to set up the Munbyn Print app and it works well. But I won’t be needing this for my label printing – just using this to print PDF address labels for my business.

    I love this brand! I had the older Munbyn printer for about 3–4 years, and it worked great, but it was time for an upgrade. This new model is not only prettier, but also lighter and much easier to load stickers into. I use Munbyn’s thermal stickers as well, and everything works seamlessly. The app is super easy to use, and the printing speed is faster than before. As a small business owner, this is an affordable and efficient way to print custom stickers. Highly recommend, great tool and definitely worth the price!

    Why did you pick this product vs others?:
    Great for any small business!! Compact, easy set up and quick printing! One of the best tools for my small business! Came exactly as described. Love the Bluetooth feature! Easy to print shipping labels or custom stickers for packaging! So many printing options! The App is super friendly and easy to use, only took a few minutes to set up and the printer was off and running! Great addition to my office!

    I just received this yesterday and it’s a great thermal printer, especially for small businesses, mobile vendors, or anyone who needs quick, no-ink receipt or label printing on the go. I had a different munbyn printer before this and decided it was finally time for an upgrade. (no Bluetooth on my last one)

    Easy Bluetooth Pairing: The setup was straightforward. Paired with my phone in under a minute, and the connection has remained stable. I had a bit more trouble with my laptop but that could’ve just been my own issues. Once installed pretty quick and easy printing.

    No Ink Needed: Since it uses thermal printing, there’s no hassle with ink cartridges. Just pop in the thermal paper roll and go.

    Print Quality: Clear text and logos, especially on standard receipt paper. Nothing crazy or different from other printers but I like it for what I need it.

    If you need a convenient, wireless thermal printer for receipts, labels, or small documents, this is a solid choice. and make sure you’re using good-quality thermal paper for best results.

    As I only got it yesterday, everything has been great and I was able to print several labels pretty quickly but I’ll update after a couple of more weeks of use.

    LOVE IT! I have been using another popular brand printer and it would never align properly so I would only be able to print 4-5 shipping labels at a time before having to manually reload it. I have an online store and sell on multiple platforms so having to manually change it was a pain and not very efficient.

    So after reading reviews, I ordered this one and very happy I did.

    Easy to set up, does not hook up thru iPhone bluetooth, need to upload app and connect via the app. Once set, easy peasy.

    The app is far more sophisticated and functional than the prior minimalistic app for other brand printer.

    I have printed both shipping labels and imported my logo for product stickers which both worked seamlessly, no having to realign labels as this does it automatically. Such a relief.

    The app has tons of templates but I have not yet used but look forward to exploring. If you are on the fence about purchasing this, do it. (I am a paying customer, not paid for my review).

    I absolutely love this little printer. It’s such a great value for the money. The instructions were so easy to read through and implement that it only took me 10 minutes to go from unboxing to printing out my first label. It worked seamlessly with my iPhone-no compatibility issues at all. That 10 minutes included downloading the app! It may look like a cute little machine but it’s a powerhouse. I ordered just a couple of label variations to try out but I already added a bunch more to my cart. I will be using this primarily to print out stickers for product packaging for my small business.
