  • Absolutely Delighted with This MUNBYN Thermal Label Printer!
Style: Bluetooth Color: White
I recently purchased a MUNBYN thermal printer, and it's been a game-changer for my home office. From the sleek, compact design to the straightforward setup, everything about this device is impressive. It took just minutes to connect to my computer, thanks to the clear and concise instructions. The print quality is outstanding—every label comes out crisp and clean. Whether I'm labeling file folders, storage boxes, or creating shipping labels, the results are always top-notch. The printing speed is also noteworthy; it handles multiple labels in quick succession without any lag. What truly stands out is the custom label function. By downloading the "MUNBYN Print" app on my phone or using the online "Munbyn Editor" on my laptop, I can easily design my own labels. There are thousands of templates to choose from, making customization a breeze. Overall, I highly recommend this thermal label printer for anyone needing a reliable and efficient labeling solution. No ink or toner needed, making it cost-effective and eco-friendly. It's made my life significantly easier and added a level of professionalism to my tasks. This is truly a fantastic product offering excellent value for money! ... show more

  • The Best Investment for My Cottage Bakery
Style: Bluetooth Color: White
The media could not be loaded. Why did you pick this product vs others?: As a small business owner running a cottage bakery, I’m always looking for tools that save time and streamline my process. The Munbyn thermal printer is a fantastic addition! Pros: One of the first things I appreciated was how compact it is. It fits perfectly in my limited workspace, or on my counter space, without adding clutter. Setup was surprisingly quick, and the Munbyn app is super intuitive. Yes, even if you’re not tech savvy. I was able to start printing labels for my baked goods in just minutes, which was a huge plus during busy prep days. Cons: The only downside (and not enough to remove a star from my rating) encountered was the initial paper setup. It was a bit tricky the first few times. It took a little patience to get the hang of loading the labels properly. Once you figure it out, though, it becomes second nature. Overall, this printer has been an awesome investment for my business. It’s reliable, efficient, and makes my labeling process so much easier. Highly recommend for other small business owners! ... show more

  • Great Quality, But Printing Issues
Style: Bluetooth Color: White
This printer has been super dependable for me, and overall I like it. The only issue I ran into was with the cord — once the original C-cord stopped working, my laptop couldn’t detect the printer anymore. I tried everything with customer service (who were really helpful and patient), and even tested other cords I had at home, but nothing worked. In the end, they replaced my printer, which was nice of them. When the new one arrived, I tested it with the old printer and realized it was really just the cord that was the problem. I wish Munbyn sold replacement cords separately, because it seems like only their cord works with this printer. It would be nice to have a backup so my old printer doesn’t go to waste. Another thing — I bought the pink shipping thermal paper from Munbyn, but it won’t print shipping labels on it. It prints other things fine, just not shipping labels, which was a little disappointing since that’s what I wanted to use it for. That said, the print quality is good, and for the price, it’s still a solid label printer. ... show more

  • Love this!
Style: Bluetooth Color: White
I love this little machine! So easy to use! I have struggled with label making for years with my candles. Smudging ink, wasting labels that won't line up properly... so frustrating!! This Munbyn label maker has been my best purchase in a while. I can create labels on chatgpt and print them out on the Munbyn. I willingly sacrifice labels with color for the ease of this printer. It takes no time at all to customize and print with Munbyn and Chatgpt. Prints fast too!! Love this product!! ... show more

I've messaged company for assistance but haven't heard back. Been theough online troubleshooting. they do reach out I'd be glad to give them 5 stars if they know a trick to fix or send a new unit. Im hoping it's just a production problem, mine is just a cracked egg out of a dozen ... show more

  • Tried multiple thermal printers and FINALLY
Style: Bluetooth Color: White
Ive tried multiple thermal printers and this is by far my favorite one, I think I might be in love. I’ve been so picky since I just want to label everything in my home, and this has been my perfect go-to. It’s so easy to connect to the app and so light you can basically carry it in your bag! The app itself is user friendly with a lot of designs that are great for any label. The quality of the ink is very precise unlike other printers that look gritty and you can change the heaviness of the ink contrast. Just try it and you’ll see, you won’t have to worry about returning it. ... show more

  • Great price and awesome printer!

I absolutely love my new printer. It was very easy to set up, and the app is very easy to use if you want to print stickers. As a part time reseller I need to print lots of labels and love that it prints so quickly. I also use it for making my own labels with my own qr code that goes right to my shopify.
