HP Officejet Pro K550 with IP Address

Last Modified: 2012-02-16
My HP Officejet Pro K550 started doing funny things after AT&T came to my home office 3 weeks ago and installed "U-verse," which I do not like at this point in time. Pre U-verse, this printer was on 192.168.2.xxx. I couldn't switch it to the new one (192.168.1.xxx), and therefore couldn't use it. Ultimately, I got rid of the old IP address, but it took on one I've never seen before, for the IP addrress, subnet mask, gateway, DHCP server, and DNS servers. HP won't talk to me about a 6-year old printer, and AT&T techs are hopeless. I have the feeling that someone out there know how to access the printer's configuration page and fix these issues. I don't even care if it's embarassingly easy, as I have been struggling with this problem for a week.
Watch Question

Is that the HP Officejet Pro K550 dtn or dtwn model?  What OS are you on?
Sergsystem administrator

Reset the network settings (HP Officejet Pro K550dtn/K550dtwn)

    Press and hold the Configuration Page button, press the Resume button three times, and release the Configuration Page button.
    Wait about 20 seconds and press the Power button to turn off the printer.
    Press the Power button to turn the printer on.


In response to the first comment, this is the K550 (no suffix). I bought it in 2006, and I'm not sure when the other models came along. Oops, almost forgot, Windows 7 64 bit.

In response to the second comment, page 25 of the manual says to do the same thing, although it doesn't mention the 20-second delay. HP describes it as a method to "reset network configuration settings." I had tried it a couple of days ago without success, but tried it again today with the 20-second delay. I will give it a few more tries, but with longer and shorter delays. After all, if HP thinks it should work, it should work. One would think.

Thanks for the shot in the arm. I will fiddle with this suggestion a bit more.
I have had problems before with HP reset issues and just did a clean install in the new network.  Go to hp.com and locate full driver/software install for this model and this os.  It's easier in the long run.
This one is on us!

Ultimately, after many hours of trying to figure this problem out because either HP or Microsoft left the "toolbox" feature out of the Windows 7 driver, the only way to change the printer's ip address (there's that i problem again) was to use an XP machine (virtual in this instance) to change the printer's settings. Though it would appear to be an unusual sort of solution.
