    David,

    Follow this link: http://discussions.apple.com/thread.jspa?threadID=2133770&start=15&tstart=0

    Half way down the page is a post about how to change the ip on your printer. However, you need to have a computer which can access the printer. Your apple is obviously not seeing the printer...

    That should do it.


    Eric,

    Thank you very much for taking the time to help.

    I see those instructions but have one question: Will I still be able to use Ethernet to connect to the Internet as well as print? (My HP 4050N is connected to my computer by Etherenet via an Asante hub, to which my cable modem is also connected.)

    David,

    Everything else will work fine. All you will be doing is changing the ip address of your HP printer. Your mac is not able to see it. I'm not sure why, but changing it to an address which your mac will be able to see is what you'll be doing. I don't know how many other devices are on your network, but you don't want to have two devices with the same ip address. I should've asked before all this, but did you first try to just use the install printer/ip in the preferences menu? Are u sure you need to change the ip on your printer? Can u "ping" the printer right now?

    The only devices currently on my network are the printer and the cable modem.

    I did try to install the printer (many times) using the Preferences menu. I had been following Ted Landau's instructions in his MacWorld article, but they didn't work for me <http://www.macworld.com/article/142631/2009/09/snowleopard_printing.html>.

    When I ping the printer at the cold-reset, default IP address (192.0.0.192), I get the result, "56 data bytes." Is that good or bad?

    David

    What does it say after 56 data....

    If it says "timeout ....." then the ping has no been received and acknowledged. Then you may have the same problem.

    U can email me at eric@tge.com for further help...

    Eric,

    Correction: When I ping the printer, I get the following results:

    56 data bytes
    Request timeout for icmp_seq 0
    Request timeout for icmp_seq 1
    Request timeout for icmp_seq 2
    [etc., ad infinitum]

    David
  • Ponteigh Level 1 Level 1 (0 points)
    [etc., ad infinitum]


    That was supposed to be "etc., ad infinitum" enclosed in square brackets. There was no "http://"

    David
  • Jareddad8 Level 1 Level 1 (0 points)
    Request timeout means you cannot ping the printer. Your mac is not seeing the printer. Same problem I had. As I mentioned before, you will need to put another computer on the network which can see the printer and change its ip address. Maybe a PC or another mac not running snow leopard. Then follow those instructions I gave u before and change the ip to one in the range that Andrew told me to change. It's very easy to do. Then hopefully you will be able to see the printer and install it.

    Eric,

    I followed the instructions at the link you supplied above. When I changed my network address to a higher number and pinged it, I got the desired "2 packets transmitted, 0 packets received," but with the addition, "100.0% packet loss," which wasn't mentioned in the instructions.

    I tried entering that address in Terminal and pinging it anyway, but got the message, "Operation timed out
    telnet: Unable to connect to remote host."

    Sorry--I meant that I tried entering my cold-reset, default IP address into Terminal and pinging it.

    David
  • Jareddad8 Level 1 Level 1 (0 points)
    1. Did u use another computer to change the ip on the printer?
    2. I believe "No packets received" means you did not receive a packet back from the printer, which means it probably did not connect with your computer.
    3. How do you know you changed the ip address of the printer? If you cannot successfully ping it, you would not have success with changing the ip address.
    4. You must have some computer "ping" the printer. Pinging the printer just means you can communicate with the device (printer). Naturally your Snow leopard updated Mac cannot...

    Does this all make sense?

    Okay--after the 22nd try (it helped that I was listening to the compulsively repetitive overture to "La gazza ladra") I was finally able to get an unused IP address.

    But when I try telnetting to the cold-reset IP address, I get the message, "Unable to connect to remote host."

    I'm not quite sure what's happening. Can we back up a little. First, what is the ip address of the printer right now? Before you tried to change it. I suspect you haven't changed it yet. Are you using another computer? Not you snow leopard upgraded mac, right?

    Eric,

    The IP address of the printer is the cold-reset, default 192.0.0.192. I am booted from a 10.6 volume; I got the IP address by printing a Configuration page.

    David
  • Jareddad8 Level 1 Level 1 (0 points)
    10.6.1 is Snow Leopard. Like I said before, you have to use a different computer unless you can book up on 10.5.X (Leopard). Otherwise you cannot see (ping or communicate wiht) the printer at 192.0.0.192.

    David,

    Just to jump in here for a second (and thanks to Eric for being so helpful), what is the IP address and subnet mask on your computer (you can get this in the Network System Preference). From there I can tell you what a good IP address to set on the printer would be.

    Alternatively, you could turn on BootP on the printer which should enable it to get an IP address from your router if it is not currently configured.

    Just trying to help.
