A great ink and template headache saver.
If you’re looking for a great, versatile, and FAST label printer, this Munbyn is the one. You may have to tweak the horizontal and vertical settings within the app, and burn through some practice labels before it prints where you want on the label, but it’s very easy to accomplish. Once set, it will print perfectly aligned and very fast. Highly recommend, although mine didn’t include a label roller stand, if you’re printing many labels, you may want to purchase one as the labels run through very quickly and jam up against the feed tray if you’re not paying attention.

Obsessed – I Love it!!
It took a little while to set up but not unreasonable. I think the 130s are so cute! BUT I also noticed every time you load a label is wasted. I can always paint this one so I do like the autofeed and no wasted labels. I use apple products and connecting with Bluetooth was simple. Ironically I haven’t figured out how to plug in with USB but it’s unnecessary. It prints fast. The plug is kind of huge though for such a tiny printer. I’m very happy with my purchase. The print is dark, the first thing I tested out was a poem with small words and it’s all legible I like it.Update: I have been printing labels and all kinds of things now. I like that not only does no label get water, but I did accidentally have one single sticker that had to get torn off for calibration, but I am determined for no waste, so I put the single 2in sticker back in the printer by itself. It still printed!! I need more orders so I can use this every day!Watch out: I have been having trouble getting things to align properly when trying to print from the app and it has not worked out for me. I have had to print by downloading and directly printing but getting the alignment together sometimes gives problems. ALSO, definitely get munbyn labels if you can. I wanted to try off brand but cute stickers with the printer, it works, they print and feed but there is a serious difference. it does not tear out as well and sometimes I wonder if it calibrates as cleanly.I have literally been making up things to print and was so excited when I started printing customer’s labels. It just makes your business look so much more professional.

Easy to use and compact
Small in size it fits on a small stand so you can store labels underneath. I have used it several times and sometimes with a week between and every label has printed clearly. Excellent quality and was simple to set up.

A Must-Have for Small Business Owners
Let me start out by saying this is my four thermal printer, and I am absolutely in love with it! It is so simple and prints perfect everytime!This printer is a total game-changer for my workflow. The ease of setup was impressive; I had it connected to my phone via Bluetooth and printing through the Munbyn app in under five minutes. The ease of instructions made the process foolproof. I’ve been using it for high-volume shipping, and the durability is evident, it’s built to last for hundreds of thousands of labels. Compatibility is a huge plus, as it works seamlessly across my iPhone, Mac, and Windows desktop. Most importantly, the stickiness of the labels is perfect; they bond instantly to poly mailers and cardboard boxes. I promise your going to love it!!

Super efficient remote printer
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.

The Printer Works Perfectly
When I first bought this printer, I honestly wasn’t very happy with it. The print quality wasn’t as clear as I expected — especially for QR codes — and even after adjusting print density and trying different settings, it still didn’t improve much.I contacted the seller, they asked me to share a few sample prints to better understand the issue, and after reviewing them, they offered to send a free upgraded replacement printer. I really didn’t expect that level of service, and I appreciated it a lot.The new printer arrived quickly, and right out of the box I could see the difference. The prints are sharp, the barcodes and QR codes scan perfectly, and the setup process was simple and smooth. I’ve printed several batches of shipping labels now, and every one looks professional.Throughout the process, the customer service team stayed polite, professional, and genuinely helpful — something that’s honestly rare these days.Overall, I’m very happy with how everything turned out. The replacement printer performs great, and the company clearly stands behind its products. Highly recommend both the printer and the seller!

No lo recomiendo, tiene mala calidad de impresión. No me funcionó ya que el código de barras se pega ya que la impresión no es nítida. Sugiero invertir por una impresora de mejor calidad, en ocaciones no es tan diferente el precio.
