auto-discover of network printers relies on ip6?

I hadn't even thought of looking at the printer config, but no:

TCP/IP        Enabled
  IPv6        Disabled
SMTP          Disabled
NETBIOS/IP    Enabled
IPP           Enabled
FTP           Enabled
mDNS          Disabled
APIPA         Disabled
SNMP          Enabled
Web Server    Enabled
TELNET        Enabled
