HP DeskJet 3755 printer offline, unable to communicate with the device

[User09082022]

Hello, My laptop is connecting to the new Wifi in my house. Now my printer is not working.

I tried to reconnect the printer to new Wifi, and also tried to reinstall the software through"HP Easy Start." But, on the step "Add and Verify",  my laptop couldn't add the printer to the system preferences "Printers & Scanners" list. I received the message "unable to communicate to the device" . I know the problem is because my laptop connected to the new Wifi. Could you teach me how to fix this problem? make my printer connect to the new wifi?

Hi @User09082022,

Welcome to the HP Support Community

I understand you are facing a connectivity issue with your HP DeskJet 3755 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, and 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

Once the blue light is solid try adding the printer using Airprint drivers.

Add the printer using Apple AirPrint drivers.

1.) Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

2.) Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer.

3.) If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button at the bottom of the list.

4.) Click the plus sign click Add Printer or Scanner, click the printer name.

5.) Click the Use or Print Using menu, select AirPrint in the pop-up menu. Then click Add.

6.) Try to print.

Hope this helps! Keep me posted.
