Find network ports given IPs

I have about 60 printers scattered over a large network. I finally have the goahead to move them over to their own VLAN, but need to know what ports the printers are plugged into so the new VLAN can be assigned. I know how to find what the port is for an individual printer based on the IP by finding the MAC address, but rather than each printer individually, is there a good way to find this information for all at the same time? Switches are all Cisco.

Use a switch port mapper application to pull that information from your router's arp and switch mac address tables. I believe Solarwinds still offers a free one or at least a trial.
