It appears you have one or more static IPs assigned because they are not sequential. I would check these settings and subnet masks on both the printer and PC. You can run an 'arp -a' command before/after a ping to see if the printer shows up.
my pc ip config,gateway not core switch iP, ping printer is ok
iP address : 10.0.9.20/24
gateway : 10.0.9.2
