Thermal Printer USB Label Printer Thermal Label 4x6 for Shipping Compatible with Windows, Mac OS and Linux systems

It expected it to be good and it is good. Device quality is more than decent and print quality is as good as it gets (thermal printing quality depends more on the paper than the printer). I wish it didn't have to come with additional power supply brick, which has a very peculiar plug. Still, as long as it works, it's no problem at all. Two things that might help. First, the MacOS driver from the website is obsolete and does not work. The driver from USB that came with the printer works fine. Quick installation and it just works. The driver comes with some funny spelling errors, that tell a story about quality control. The company seems to be more focused on hardware than software, but fortunately in this case no software is needed beside the driver. Second, it is designed to take 1" diameter paper rolls. But it does work with more standard 1.5" rolls. Bigger roll does not sit very tight on a smaller axle, but it does not cause any problems. After initial setup it is wonderfully useful and comfortable device. Quick to use, fast, efficient and not loud. It's ready to print instantly and you need no extra work - no manual loading paper, no ink replacement, no waiting for it to warm-up. Paper rolls inside the device really make a difference. It makes you want to print tons of labels and stick them everywhere. Which I do.

Bought this for selling random bits on Ebay and it works brilliantly, labels are clear and nice and sticky - easy set up with minimal faffing. Comes with a few labels but I'd recommend buying a roll with it depending on how often you'll use it

Fanatsic purchase, easier setup than our Zebra that was 3 times the price and just as fast/good quality

Printer has nice curves, a viewing window to see how much of the roll is left, works on USB. Print out is reasonable enough for standard postage labels with QR codes, barcodes and text. Perhaps not the one if you want detailed branded prints. I found setup on PC with USB cable OK, but not great. The 'windows diagnostic' software is required to make the printer calibrate itself to the roll - you might need an emulator to do that if you're MacOS, Android or Linux. My thoughts were - USB no network - I'll share with a Pi printer server. No luck. With CUPS it is text only (no PDFs, ZPL format only) and with USBIP windows wouldn't talk. So I've used VirtutalHere to USB share it to my network, which means having VH client on each device that wants to send to it and only having 1 client attached at a time. In short, using it as a network label printer is not ideal, as you cant have multiple people queuing prints - they have to take turns having it virtually attached. The most annoying thing for me is that the device driver is installed via an EXE not given as an inf AND Vretti dont make it obvious that the 420B USB only needs the 4BARCODE 4B-2054M driver. Yes it's in the manual, but why not put the model number in the driver name (and just given me an inf).

Easy installation both on my PC and on my phone, perfect and clear printing, it's better, than I expected! It's compact size saves me a lot of space on my desk, I can't wait to start using it!

NB I think this listing has changed since I made my purchase at the end of November 2022 - I bought the Bluetooth version. Also…I initially wrote a 1 star review as the printer simply wouldn’t work, but I later updated the score to 4 stars and amended my written review as described below. However today - 17th September 2023 - I am updating the score to 1 star and adding further comments at the bottom of my review. I did a lot of research before buying this printer and I chose this one because it had all the features I wanted (Bluetooth printing, can take different sizes of labels, labels stored inside the printer, compact, easy to use) at a good price. However, it ended up being a huge let down at first. Although it was easy enough to download the app and connect to the printer from my iPhone, I just couldn't get to grips with printing a label successfully. The instruction manual is in poorly translated English so it's not particularly helpful, and the app is not intuitive and parts of it are in Chinese so it's pretty useless. I was able to import a returns label but for some reason whenever I tried to print it the printer would think about it for 30-60 seconds and then spew out a tiny QR code as shown in the photo. The code isn't even related to the label I was trying to print; when I scan it it comes up as '123457789', so it must be a test code or something. I tried asking for help but got no reply, so customer support is completely lacking. It was so frustrating to continuously waste labels so I decided to give up and I intended to return the printer for a refund. What a waste of time and trouble. However, I decided to give the printer a final try (if only to print its own return label!!) and it suddenly started working properly. I didn’t do anything differently; it was as if the printer all of a sudden wanted to play ball for some unknown reason and I can’t say I was unhappy about that! Now it prints labels in a matter of seconds and I’m absolutely thrilled. I may need to play around with the thickness of the printing as some of the barcodes can look a little thick…but that said they still scanned without issue by both Evri and Royal Mail so perhaps I’m better off leaving well alone! The fact this printer is black is a big plus to me as it looks slick and it won’t change colour over time (I hate how white plastic so often yellows as it ages). I would have liked it to come with a few sample labels for practice runs, but I’ve not marked down for the fact it doesn’t as this is mentioned in the listing so it came as no surprise. So if you have a similar experience to me at first, don’t despair as hopefully your printer will suddenly buck up its ideas like mine did! UPDATE 17/09/2023 Please do not waste your time and trouble on this printer. I have spent the past 3 hours trying to print a label but the printer does nothing. I started experiencing issues a few weeks ago when the printer spat out blank labels. I cleaned the print head with isopropyl alcohol as directed but this did nothing. Eventually after many tries it did print something but it was partially off the page and I had no idea why. I had set everything up as normal but for whatever reason the printer decided to play up. I reprinted it several times, each time adjusting the position so that finally it did print fully on the label, even though on my phone's screen it was showing as hanging off the page. So bizarre. Today I have gone to print a label and it spat out blanks again. I cleaned the print head; no change. I reinstalled the app; no change. The app keeps telling me 'printing completed' but I'm still sat here waiting for my label to print. It is so frustrating and it has wasted so much of my time. When it works properly this printer is great. But when it doesn't work the app compounds your frustration and exasperation by acting as if nothing's wrong. No error messages or anything to help explain the problem. Please save yourself the same hassle and inconvenience - don't buy this printer!!

I bought this as i was sending a lot of personal homecoming gifts and fed up of printing labels and running out of ink. Easy to set up, quick printing and perfect for those sticky shipping labels. Best buy for me

Easy to connect following the instructions provided. Good print quality.
