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

    I had not even thought of telnetting to the printer.

    Trying it out, I find it a bit cryptic.

    $ telnet
    Connected to
    Escape character is '^]'.

    I had never heard of JetDirect until yesterday; so I'm still a novice.
    I "think" this printer has the server attached where the ethernet cord
    plugs into the side.
    Hmmm... I didn't "configure" JetDirect, so, I must be using whatever
    defaults my friend had previously set.

    I am a bit worried that the printer for both my friend and for me
    was at a seemingly static IP address of

    Yet ...

    I have DHCP configured ... so I'm shocked that DHCP just happened to
    give the printer the *same* IP address it had at my friend's house.

    So, I'm a bit worried that the IP address configuration is not obvious
    to me. But if it works as it is, I'm ok with that. I hope.

    How can I tell if my JetDirect is using a STATIC or a DYNAMIC IP
    address anyway?

    I must admit, I was just shooting blindly, but, looking back, I never
    did "configure" the printer.

    All I did, in effect, was clumsily click on the operating system GUIs
    for configuring a networked printer.

    Reflecting back, this is what I did:

    1. I plugged the printer ethernet port into the router; nothing happened.

    2. Dumbfounded, I clicked around in Windows XP like a foraging ant
    searching for crumbs, and, at one point, the wizards favored me, and the
    printer showed up. http://i41.tinypic.com/vi39lt.jpg

    3. I then did the same for Windows 7, and again, the wizards eventually
    favored me for having clicked enough buttons.

    4. I did the same for Linux, and yet again, the wizards allowed me to
    print. http://i40.tinypic.com/2r4ika8.jpg

    Point is, I never did 'configure' anything as I took all the defaults.

    I would never have known (especially on Linux) what to put in the fields

  6. so have you discovered how to make the print darker?

    All I know, at the moment, is how to make the thing print. :)

    I never explicitly downloaded any drivers as I let the operating system
    figure all that out. I never changed anything from the default yet.

    I'm not even sure WHERE to go about looking to make the print darker,
    since the HP LaserJet 2100TN has only two buttons, and no display.

    I do have the user manual, so, I'll comb through that.

    The printer is configured for that address, so it doesn't use DHCP to get one.

  9. I always shoot for PCL v6 and if I have a problem, I'll downgrade to PCL v5

  10. In the Telnet session you can hit the key; "/" { no quotes } for current
    settings, and hit "?" top see a list of interpreted commands.

    For example the following line will disable IPX/SPX { you may not see what
    you type }

    ipx/spx: 0

    Success is shown by the showing of an additional ">" and then you can hit
    "/" to see that change was made.

    Typing "quit" will Save the configuration and close the Telnet session.

    A way to test printer communication is by a Telnet session to port 9100
    For example if the JetDirect IP is you would type;

    telnet 9100

    That will open up a Telnet bsession with no feedback. just type anything
    and everting and include hitting the "Enter" key.

    When you close tghe Telnet session, whatever you type in the Telnet session
    will be printed by the printer. This is a good way to test the Print Server
    at a low level.

  12. That can be determined using Telnet or HTTP.


    Hit the "/" key.

    If it shows "DHCP Config : Disabled"
    It is a static address.

    It seems Linux defaults to PostScript, and Windows defaulted (with my
    selection choice of the available drivers) to PCL v6.

    So far, it's working.

    Of course, I still have no idea how to make the print darker; but it
    appears to be dark enough for now.

    You're not kidding there's no feedback!
    I had to reboot the computer to kill the session!

    I see now that there is that one page, under Administration->Configuration
    where you *can* actually change things.

    Which of those settings would be suggested to change though to make
    the print be darker or the network connection better?

    a. Protocol stacks?
    b. TCP/IP settings?
    c. IPX settings?
    d. Snmp settings?
    e. Internet printing? (whatever that is)

    I guess not using DHCP is OK with me (as long as it works).

    The funny thing is that the printer configuration pages all say that the
    printer *is* using DHCP:

    But, it can't be using DHCP since it's always, which
    wouldn't happen if it *was* using DHCP.

    So, I'm confused ...

  17. Have your News Reader (NNTP client) relist all the news groups on that news
    server and then find; comp.mobile.android

    It is available on GigaNews and NewsGuy.
    David H. Lipman, Sep 8, 2013
  18. Sure, they work. However it may not take full advantage of the printer's
    capabilities. I have managed manyh HP LJet 2100 and they are limited in
    capabilities so it isn't an issue with that printer.

    The funny thing is that the printer *appears* to have a static IP address
    of; yet, DHCP is clearly enabled as shown in the web browser
    pointing to

    Your nice telnet suggestion above also confirms DHCP is enabled:
    $ telnet
    Connected to
    Escape character is '^]'.

    Actually, while I downloaded the printer drivers from the HP web site,
    what is missing is how to set up the printer on the network.

    For that, I used the respective operating system wizards (WinXP, Win7,
    and Linux).

    Interestingly, each of these wizards obtained the HP drivers on their
    own, so, in the end, I never used the HP drivers that I had downloaded.

    I have no idea what the *practical* difference is between the drivers
    anyway (e.g., PCL5 vs PCL6 vs PS); but, all I know is that the printer
    appears to now be networked to all the devices except the Android
