Asking for user name and password when printing

[Tryinhard]

I have tried to get my HP Office Jet Pro 7740 to work with Mac and its latest OS. It is a nightmare.

How can I reset it to factory settings to start from the scratch?

I could help you sort this out 😊

I will require few details to be able to assist you better

- Are you trying to connect through USB or wireless?

- Do you have any Anti-virus software installed on your MAC?

If you are trying to connect wirelessly please check these details

- Ensure the printer and the MAC are connected to the same wireless network.
-Note:- This printer supports only 2.4GHz network. Do not connect it to 5 GHz Network incase your Router supports both 2.4 and 5 GHz
- If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, then 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.

Please 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.

Also check for WiFi interference and perform a ping test using the Mac Network Utility and let me know the results. Use the printer IP address to perform a ping test, the printer IP can be located by touching the wireless icon on the printer display or by printing a Network Configuration Page

Meanwhile please your Printer and Mac have all the latest updates

If you wish to go ahead with the Restore, here are the steps

1. From the printer control panel, touch or swipe down the tab at the top of the screen to open the Dashboard, and then touch ( Setup ).

2. Touch Printer Maintenance .

3. Touch Restore.

4. Touch Restore Factory Defaults. A message appears stating that the factory defaults will be restored.

5. Touch Continue.

Keep me posted 😊

Thank you for the most comprehensive instructions so far. However, I still have the same problem. Can not print, but scanning works over the WIFI.

This might be an Mac issue, I will check it by trying the same with PC.

Please try with a PC and check if it works.

You could also try printing using HP Smart App for Mac: https://support.hp.com/in-en/document/c06188214
