Try a broadcast ping, and see who responds. One of the responses from an address you do not recognize as something else may be your print server. Example: # ping -b -I eth0 192.168.100.255 WARNING: pinging broadcast address PING 192.168.100.255 (192.168.100.255) from 192.168.100.32 eth0: 56(84) bytes of data. 64 bytes from 192.168.100.29: icmp_req=1 ttl=64 time=0.597 ms 64 bytes from 192.168.100.18: icmp_req=1 ttl=64 time=1.39 ms (DUP!) 64 bytes from 192.168.100.41: icmp_req=1 ttl=64 time=9.20 ms (DUP!)
