Zebra GK420d labelwriter not working on our main subnet
Posted on 2015-02-17
We had a Zebra GK420d connected to our network for about a year and a half before it suddently went offline. I tried pinging the printer but without luck. Pinging it continiusouly I realized it actually made a reply 1-2 SOMEtimes when rebooting the printer/moving the cable to a different port on the switch, but quickly going offline again. I've trive multiple network cables and connection it to different switches on our main network.
I bought a new identical printer only to realize it had the exact same issues, so I tried moving it to another subnet and it worked completely fine! I tried connecting it to my home network and it works fine there as well!
I explained my problems to ZebraCare but was told they didn't ever have any similar problems, and since the problem is network related they cannot help me.
How can I make sure the printer isn't using a different IP-address right after responding to the one I assigned it? Can I hunt it down by it's macaddr somehow?
Any tips on how to proceed debugging this?
