hp250 is 'online' but not communicating

[RLKny]

I just bought an HP 250.  It recognizes my wifi network and joins it, but then my computer, on the same network says the printer is 'off line' and so I am unable to print or scan.  When I choose having the printer be a direct wifi, I have to turn my computer off the network, to switch to the printer network, am able to print, but not to scan. Does anyone else have such problems?  Please advise.   thank you!

Welcome to the HP support community

I'd like to know the following to isolate the issue further-

1) Are the printer and Mac connected to the same network?

2) Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual band has different SSIDs for 2.4G and 5G networks.

3) What is the distance between the router and the printer?

4) Is there an antivirus software installed on your Mac?

5) Could you perform a ping test  and let me know the results? Use the printer IP address to perform a ping test, the printer IP can be located by selecting the wireless icon on the printer display.

Perform a ping test to check the connectivity

1. Click Applications > Utilities > Terminal.
2. type ping "IP address" and press enter

Wait until 10 pings have been performed and then press ctrl c on the keyboard and hit return. 

The results will appear.

Share the ping test results.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
