I assume you only have 1 interface. If not, select the appropriate one. Then, in the long box "using this filter" enter ether host <MAC address>. Here's an example "ether host e0:37:17:cf:b7:52". Then, with the cursor in that long box, press Enter. You should now see the captures if printing is occurring. It will list both source and destination IP addresses. This is assuming there is no router between the computer and printer.
In your case, it would be ether host A4:EE:57:73:CB:85. I thought I had made clear that this is on a lan. It goes thru an eight-port D-LINK router, as does everything else. I have tried the MAC address with capital letters as you show, and with small letters, as one of the other correspondents shows, but it bombs either way. --doug
