Deskjet 3755 Constantly Goes Offline

[ozmee]

Deskjet 3755 will not stay online.  HP does not offer any help with this either.  I just set it back up again yesterday, today it is once again offline. This is more annoying than I can say.  To have to reinstall a printer every time you want to use it is not why I bought this printer. We have Spectrum which provides us with a 2.5 and a 5.0 hookup.  Some products need the 2.5.  I need help and apparently HP decided to close down their repair business employees.  Very shoddy and I regret buying this printer more than I can say.

@ozmee, Welcome to the HP Support Community! I’m here to help.

I understand the printer goes offline. Let us try these steps:

• Restart the router, the printer, and the Mac
• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 or 5GHz network.
• 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.
• The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold the option key on your keyboard and click the WiFi icon to get detailed information.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.

Update the printer firmware

Click here to know different methods of updating printer firmware.

Also, check for any software updates on Mac

Click the Apple icon > About This Mac > Software Update and install any available update.

Perform a ping test to check the connectivity

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.

Hope this helps! Keep me posted.
