What's the trick to make Ethernet work on an HP 2100TN printer?

  1. According to that page, it is DHCP configured and thus a dynamic address

  2. Yes, it can keep the same IP even if the end of the IP Lease whas been

    OK. I found it!

    It must be a new newsgroup, as I had searched in the past for an Android

    What's interesting is that it kept the same IP address from one house to
    another, under different networks (both using as the gateway).

    Thanks David for your advice. I appreciate all your help!

    I won't go into the DHCP protocol to explain why it will stay at for a lengthy period or how a new IP could eventaully be
    assigned (Leased) to it.

    BTW: That's a HP Jetdirect 600n and the last Firmware is Version = G.08.49
    Your Telnet session shows; "G.07.20" so it could be upgraded. However it
    isn't too important and you are just learning about HP JetDirect Print

  7. No problem. I have managed a few hundred HP Printers on HP JetDirect Print

    Sure it would. It will use the same address as before unless there is a
    reason not to (eg that address is in use by something else).

    Practical wisdom is if all works the way you are satisfied. Leave it be.
    Reason to update driver or firmware is if want particular feature or
    improvement is needed according to the release note. So many folks just
    update for the sake of update's and getting into trouble. PCLs for PC,
    PS is for Mac(Apple).

    If you are curious, reboot the router and see if IP changes. Or you can
    assign fixed IP from router GUI or from printer set up. My WiFi printer
    and NAS are given fixed IP for the convenience.

    Under one submask you can have a range of IP(0 to 256) but if you don't
    have that many devices, limit it to like 0 to 20. No need to wasting
    time scanning all those unused IP addresses. My router has IP range of
    gateway one plus 15 which is enough for our home network.

    Heh heh. I've NEVER used Google Groups. I just used the Deja-News-like
    search engine to clarify that the suggested newsgroup existed (because
    when I updated my group list in my nntp client, that group still had
    not shown up).

    Once I confirmed that the group actually existed, I realized there
    was a problem with my nntp client group list.

    So, I manually deleted my nntp client & newsgroup files, and re-installed
    the nntp client and lo and behold, when I refreshed the group list,
    that suggested android group FINALLY showed up.

    I'm not sure WHY it didn't show up before. Maybe it's a new group?
    But, it seems active - which is all that matters.

    Thanks for that suggestion, and all your other explanations!

    Is the "JetDirect" print server this "box" sticking out the
    side of the printer?

    Or is the JetDirect just firmware running on the motherboard?

    Yes, it is. It was created only a month, maybe two months ago.

    Ah. I see. I start at and let DHCP assign the addresses.
    I don't have 16 PCs and phones, so, I guess there's nothing stopping
    the printer from keeping its old address (from another home) of then. Even with DHCP.

    Thanks for that foreknowledge.

    I'll probably keep the "JetDirect" at the current version unless I know
    of a reason to change it. I don't want to have to reconfigure the windows
    machines if I don't have to. I'm not sure what's transparent and what
    isn't, to the windows and Linux machines.

    BTW, I think "this" is the JetDirect box on the side of the printer:

    I can't count the number of times I've worried that I've bricked
    a device simply upgrading it to the latest firmware.

    So I don't disagree with you.

    Ah, that might explain it then.

    Your linux method looks near optimal.

    to end a stuck telnet session: ctrl-] Q enter

  19. Yes, inside that metal cage and under that plastic door.

  20. Well I have upgraded hundreds of JetDirects with no sequalae. Either using HP Download
    Manager or via HP Web JetAdmin over TCP/IP or with the printer connected via USB or
    parallel port. I keep HP Download Manager on my notebook with all the JetDirect Firmware
    files so I can download the latest Firmware to client printers as needed.

    If the printer has power and you leave it alone for the time it takes to download the
    Firmware to the printer, it will work as expected.
