No communication message on macbook air to hp deskjet ink advantage 3835

[Sonja777]

My Macbook Air was working fine and communicated with my hp deskjet ink advantage 3835. But suddenly I get the message that there is no communication between the 2. I have deleted and reinstalled the driver software. I have also rebooted the wifi connection and restarted the macbook and printer.

Hi @Sonja777,

Welcome to the HP Support Community

I understand you are facing a connectivity issue with your HP Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist you better:

• Is the blue Wi-Fi light solid on the printer? ( if the Wi-Fi Light is blinking then please re-connect the printer back to your Wi-Fi router - Restore Wi-Fi setup mode on your HP printer, Once you restore the network to defaults, then please follow the instructions on this link to connect the printer back to your PC.)
• How far is the printer located from the WiFi router?
• Do you have a dual-band router?
• 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 networks.

While you respond to that, Let's perform a power drain:

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove the USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle
