Can't give my printer a static IP

I’m using a ZD421 and the Zebra Setup Utility. I tried several times already, clicking on Connectivity Settings, putting it to static and entering an IP. When I print a configuration report it still says DHCP and either 0.0.0.0 or a APIPA address. I also tried reaching the web server by giving it a DHCP address (which it took) but I couldn’t reach a web interface.  Are there any other methods to assign Ips or could there be something i´m doing wrong?
