New router, HP Laserjet 200 won't accept the new 14 character password

HP Recommended
HP Laserjet 200 color M251nw
macOS 10.14 Mojave


Thanks for the help you can give me.  I upgraded from DSL to fiber optic cable for my modem and router this week.  I have been able to access the new network with all my devices except my printer.  I have followed all the instructions on the HP website for enabling the network on the printer, and have put the password (which is 14 characters) into the printer on the touch screen.  But it always fails to connect.  Is the problem simply that the printer (which is at least 10 years old--very dependable) too long for the capacity of the printer?  Or is there another way to actually get the printer on the network?  [The printer sees the network, it simply doesn't accept the password.]


Again, thank you for your help.

Hi @DB298,


I'd like to help!


To assist better - 

  •  I would like to know, is your router set to work on 2.4 GHz network or 5 GHz network band?
  • What is the status of the wireless light on the printer, steady or blinking?
  • What is the distance between the router and the printer?

Meanwhile, try the steps below to connect the printer to the network.

  1. From the home screen of your printer control panel, touch the Wireless icon .

  2. Touch the Setup icon .

  3. Touch Restore Network Defaults or Restore Network Settings, and then touch Yes to confirm your selection.

  4. After the default network settings are restored, touch the back arrow, touch Wireless Settings, and then touch Wireless Setup Wizard.

    The printer searches for available networks.

  5. Touch the name of your wireless network.

  6. If your wireless network does not display in the list of wireless networks, touch Enter New Network Name, and then type the name of your wireless network.


    Type the exact network name, including any uppercase and lowercase letters.

  7. Type the WEP or WPA key (network password), and then touch Done.

    If you do not know your network password, go to Find Your Wireless WEP, WPA, WPA2 Password..

    Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.


Hope this helps! Keep me posted.
