Since this example utilizes a statically assigned IP address, it is not necessary to call Ethernet.maintain().

I tested this against a Linux VM running dhcpd and a VM running Extreme Networks XOS with its DHCP server enabled with 30 second DHCP leases. I monitored the Rx with Wireshark and no DHCP-related packets were ever sent from my Arduino ethernet shield (renewal requests, or otherwise.)
As an additional investigation, I also tried the switch statement from the DhcpAddressPrinter.ino example and it fell through to default case, indicating that Ethernet.maintain() returned DHCP_CHECK_NONE.
As far as I can tell, this function call isn't necessary, although I suppose that it is possible there is some feature I am not aware out there related to DHCP that would need to be enabled server-side.
