Well, it looks like I found the device that was sending out the martians headers. It is the Netgear print server I picked up el cheapo at CompUSA. It sets up an smb share for my HP1100A so I don't require that a particular machine is on in order to use it.
I discovered this by unplugging the network cable for awhile and seeing the martian headers messages stop hitting my logs. Now to figure out how to either get my machine to ignore them, or get the print server to stop sending them. -- Greg
