ZEBRA GK420d Direct Thermal Desktop Monochrome Printer Print Width of 4 in USB Serial and Parallel Port Connectivity GK42-202510-000

As a Mac user, I was worried about the installation process after seeing some negative reviews here. After printing a couple of test pages, it was only printing on the first 2" of a 4x6" label. Luckily, I found another review that mentioned calibrating the printer to use a specific label size, and figured out a solution!If you're using this printer with a Mac, follow these steps:1. Plug in printer2. In System Settings > Printers & Scanners, click button: Add Printer, Scanner, or Fax.3. Select the Zebra printer4. Click the Choose a Driver dropdown and choose Select Software. From the list, select the ZPL driver. Then click Add.5. Here's the magic: On the printer, press and hold the button (to the right of the status indicator) until the indicator flashes a "double-blink." It blinks once, keep holding, then it'll blink twice rapidly, let go. The printer will slowly feed out a label, calibrating the size.6. Done! Enjoy an excellent printer!Hope that helps someone else. The CUPS interface can be confusing for anyone who isn't very tech-inclined so installing with the above steps should save you that trouble.So far print quality is pretty good. Thermal printers aren't meant to print photo-quality or even super-dark blacks. It's much faster and quieter than the old Zebra it's replacing, and looks 1000x better in my workspace. I snagged it on Amazon from the Woot seller for just $34, worried there must be something wrong with the model, but it's brand new and works great. Strangely, it included two different power cables, both European and not for US plugs, so I have to using my own computer cable from the transformer to the wall. But for the price I can hardly complain.

I was nervous buying a used printer but am so glad I did! Setup was super easy and it works great!

had the previous generation for 5 year and loved it. this one is even better than the last one with better driver, speed, its more quieter, heavy duty,........etc. purchased 2 more after getting a good taste of GK420d. its compatible with UPS, stamps.com, worldship, windows 10, windows 8, windows 8 pro, windows 7, without any issues so far. will update the review if anything else came up.

Obsessed with this thing. We ship eBay items probably 3-4 times per week and this label printers was WELL WORTH the price. Lots of settings, no ink required, customizable, works with both my Mac and my PC I legitimately believe this was my best purchase of 2020 and I purchased a LOT of things in 2020

Pros: Feels sturdy, roll is encased in printer, prints very quickly.Cons: I couldn't get it to work properly. I have a mac, and the driver software included is windows based. Zebra does not have ANY download options for Mac drivers. Which is OK because macs have printer drivers preinstalled - including ones for this printer! Unfortunately these drivers only allow for the most basic of options (such as setting the paper size). If you want to change the print speed or type you have to use CUPS.Which is okay too - unless you have literally ANY issues. Such as the printer only printing on the top 1" of labels no matter what the paper size or line weight is set for. This requires a factory reset / recalibration ...which you do not have access to unless you buy a third party software. Either a lump sum of 1/3 the printer cost, or a tidy sum monthly. YUP if you have ANY issues and are using an apple device you will have to pay to resolve them with a software provided by a different company. You do not have access to those settings automatically. Windows users however do, with the free downloads provided by Zebra.So basically - if you plug this in, and it works, you are golden. For me it did not. It only printed on 1" of the labels, no matter what changes I made. I spent two hours troubleshooting, reinstalling, and wasting 50+ labels before giving up because the only solutions I didn't try required paying for additional software.Ended up buying another Munbyn printer (returned the first one due to problems) it isn't as sturdy and maybe it won't last, but setup took 2 minutes instead of 2 hours...and it actually works!

Does not function perfectly. Sometimes misses items entirely that must be respooled. Lid closure is a bit loose so often requires a little pressure on the lid to print. Works right on it's own about 40%, and with gentle pressure on the lid about 85%. For an older model, refurbished, 85% with a small tweak isn't bad.

Prior to purchasing this I had to print my labels on a laser printer, cut them to size, and affix with tape. So this Zebra printer really saves a lot of time and certainly is more professional. For some reason I had problems getting the label to print correctly, but I phoned support and got immediate help. The tech walked me through a couple of changes in my set-up and everything has been fine since.Before buying it I read some reviewers' comments on poor print quality. Although not laser quality, I've had no issues with the print quality being substandard. There are some adjustments, or choices, to make regarding print quality when setting up the printer for the first time, so perhaps it has to do with the choices there.I wish I'd bought this a long time ago, but I'm glad I have it now.
