Re-connecting printer to router every time I want to use it - now unable to make re-connection

[GBean]

Purchased printer 1 week ago.  Setup and connected fine first time, was able to print.  Unplugged printer after use.  Tried a few days later and although the wireless connection existed, the printer appears offline in the app.  Re-starting the router and laptop fixed this issue first time.  However a few days later, I am now unable to get the printer back online using the same method.  A re-start of the router, laptop and printer does not work.  I have also looked up help video's regarding assigning a static IP address, however, when I enter the I.P. address in to my browser, nothing happens.

I've now tried restoring my factory settings.  'Forgetting' the printer on the app.  And had intended to try setting up from beginning.  However I now receive the error message - 'you are connected to a 5GHZ wi-fi network, this printer can only be connected to a 2.4GHZ connection for this computer'.  Which is odd, considering I was previously connected to it and printed from it.

@GBean, Welcome to the HP Support Community!

I understand your concern. However, this model printer does not support a 5GHz network. You will have to connect it to a 2.4GHz network.

Product Specifications for the printer can be found here.

• Make sure the printer and the MAC are connected to the same wireless network.
• As this printer supports only 2.4GHz network, the MAC should be on the 2.4GHz network too.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Use WPS to connect the printer to your wireless network.

1. Locate the WPS button on your router, but do not press it yet.

   If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

2. Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

3. On the printer control panel, press and hold the Wireless button  for at least 3 seconds or until the wireless light starts to flash.

4. On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

   NOTE: The printer stops searching for a WPS connection two minutes after the wireless button is pressed. If you were unable to press the WPS button within that timeframe, attempt these steps again.

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

You may check the connectivity between the devices by a PING test

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. On the MAC Go to Spotlight > search for Network utility > select Ping tab > enter the IP address of the printer in the box
3. Check the second box that says Send only > 10 pings
4. Click on ping > Check the results at the end if any packets are lost
5. Note: There should be 0% packet loss, share the results in your next post.

Note: This printer is AirPrint compatible, you may install the printer using the AirPrint driver on the MAC as shown in step 2 of this document - Printing with Apple AirPrint

It is recommended that both the devices are up to date with their software.
