The Zebra is truly the real work horse.
If you're doing any sort of serious mail order, retail, or warehouse business, this is a real must. There are no shortage of competitors, virtually all of them under the hood are clones of the Zebra printer. You'd literally use the same print driver when you install them.
With the GX420D version being phased out by large business in favor for the newer ZD version revolving around EOL enterprise level service support contracts. Everyone else, the GX420D is a perfectly good printer with all the right technologies. Primary the various network printing interfaces you can choose from, and you should always use this printer as a network printer, and only use USB for programming purposes only. You can choose bluetooth or wifi version, personally I view the Ethernet version is the best overall option for try and trued networking that is less likely to run into issues. If you intend to use this printer primary as a USB printer this is not the printer you want. Go get yourself a LP-2844 for a fraction of the price. Where this printer shines is the networking capability.
A couple of things you should do when you get a used one of these printers you're going to have unwanted customizations on it that you want to clean up. Make sure you've installed all the manuals, and programming tools (Win only) from Zebra, including the latest version of the firmware. Do a factory reset, and flash the firmware over writing anything that might be included. Configure your printer using the software to your liking and give it a static IP address. From there on, all the future administrations can be done via it's built in web interface, and set up your workstations to talk to the printer via IP network printing.
Only catch is finding a good vendor who does put in the efforts to clean up and QC them before putting them on the market. If you're shopping around for a used direct thermal printer. Get the GX420D, you won't regret it.
