## Description

Product description

Review: Be sure to calibrate if using with a Mac! - 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 printer 2. In System Settings > Printers & Scanners, click button: Add Printer, Scanner, or Fax. 3. Select the Zebra printer 4. 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 desertcart 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.
Review: Nice Printer - 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.

## Questions & Answers

**Q: Does this printer print receipts? Also, is it compatible with scrap software for a scrap metal yard?**
A: The ZEBRA GK420d Direct Thermal Desktop Printer can print receipts and has a optional cutter that can be used to cut the paper between prints. You will need to use the Zebra designer software for this printer to work.

**Q: Can you use any brand labels or do they need to be Zebra brand?**
A: Any brand label is ok as long as it is compatible with this printer.

**Q: Could I use this printer with regular roll paper if the dimensions are the same? Labels are relatively expensive.**
A: Don't believe you can.  When I was looking for "Direct Thermal" labels, I had to find that specifically.  Just know that this printer doesn't have a ink cartridge.  It burns the information onto the label.  It's really fast too.  If you try the labelvalue.com, they are pretty cheap.  The guy I replaced at this position used this printer for about 6 years and it was still functioning well.  That's why I chose it.  Let me know if you have any other questions.

**Q: does this printer have serial port?**
A: The Zebra - GK420d connects via USB, serial, or parallel port.
