I'm not sure if this is allowed on this forum, but we are selling two of our Zebra GX420d (usb / ethernet) printers that we have used with RockRMS as we have a surplus of them. We've only printed about 20 labes on each, and they are in perfect condition with original packaging. Selling for $300 each. You can email me at tech@volunteerparksda.org if you are intersted.
