Can not print from iPhone XR to OFFICEJET PRO 8210 VIA WIFI

[CNTX8210]

For the past 2 years, I have been able to print documents from my IPAD to my Officejet Pro 8210 Ink Jet printer, ( as well as my 8100 ) with no problems.

Suddenly this week, I can no longer do this.

For the record, my IMAC27 is sitting right beside the 8210  connected via USB cable. No problems what so ever.

Router is TP-LINK AC7150.

My IPHONE is model XR.

My IPAD is Air 4th generation.

My MACBOOK PRO now says "printer offline"

Previously, on the device, I open a document to print. Choose printer, press OK and off it goes, printing.

Now when I press OK, i get this very cryptic message:

Incorrect Name or Password for HP OFFICEJET PRO 8210 .......

"Enter your user name and password.

"Name: guest

"Password: ________

"Remember this password in my keychain, checkbox"

Cancel or OK

I have no Idea who or why this  GUEST request  happens.

I have gone through several troubleshooting exercises from HP, Apple, even the court, to no avail.

Makes no sense to me.

Anybody have any ideas ?

@CNTX8210, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to print wirelessly.

• Restart the router, the printer
• Make sure the printer and the iPhone are connected to the same wireless network. Connect it to a 2.4GHz 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.
• 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.

• This printer supports WPA encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK

For more info on printing from iOS device, refer to - HP printer setup (Apple AirPrint for iPhone, iPad)

Hope this helps! Let me know how it goes.
