If your printer worked with an ethernet connection off a computer, it will work with an ethernet connection off a wired, or a wireless router - in my case, the Airport Extreme to the Airport Express. The problem was Appletalk, abandoned in Lion. The IP system obviously bypasses that limitation. http://gigaom.com/apple/how-to-resurrect-your-appletalk-printer-in-snow-leopard/ http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=bpj02326#N108AA Not being the least bit familiar with the secret network expert lingo, I didn't know what some of the terms meant. It was eventually understandable. The byte number you are asked to set in the directions is the corresponding value in the address. For instance, the first byte number is 10; the second, 0; the third, 1; the fourth,150 The printer's IP address is: 10.0.1.150. you have to set this. It apparently is tradition to use the 150 number. The SM BYTE number is the subnet mask is: 255.255.255.0 (press the minus button to go up from 0 to 255 :-) ) The syslog server address, the router to which the printer is connected, is the LG BYTE. This is the IP address of that router. You should be able to find it through software. I used Airport Utility, where you have to set up that adjunct router anyway. Make sure you have set it with a fixed IP address. I don't know if using DHCP will confuse it. The default gateway or GW BYTE is the main router you use. For me this was my Airport Extreme. Mine is set to 10.0.1.1 . I suppose if you were an IT professional magician you could play about. Or correct me. :-)
