Thank you, DeBaas. Between your input and some info from HP, I have the IP of the JetDirect. Now I know the IP of the JetDirect, and the printer setup would let me use that, but it is not in the normal
LAN range, as you have surmised, and that setup doesn't work. It is 127.0.0.1, which I can access via the browser, and it comes up with "The Server is alive and working."
I need some fine detail to take action on your instructions, quote: "When the IP is outside the range of your network, change the IP number from one of your PC's manual to the printserver range and change the server's adres to a manual IP fitting in your network. Don't forget to set back the settings from your PC. I'm afraid if I goof up, I may make an IP unreachable, so I'd appreciate your "leading me by the hand"
as it were. Of course the LAN range starts out with 192.168.x.y, and x seems to be always 0 or 1. This computer comes up as 192.168.0.100.
I have looked up the man page for route add, which told me to use ip route, but I'm afraid I'm snowed by the man page!
Please note that (AFAIK) this computer and the other two on the LAN use dynamic IPs. I don't know if that matters, but I thought I'd mention it.
It appears that the JetDirect will be set to a static IP, is that correct?
I will try to incorporate whatever you suggest on the 28th, barring any interference from hurricane Sandy. (I'm on Long Island.) Thank you once again.
