Printing on shared printer: "hold for authentication" notice. Cannot print because of that.

Hi All.

This is a common problem that just began for me. I use an Epson P900 printer connected via USB to an M1 Mac Mini. Until a few days ago, I was running OS Monterey, but installed OS Sequoia. I'm also up to date on any Epson software. In my home office my wife has an M1 MacBook which network prints from the Epson. After my OS update, whenever the MacBook calls for printing the print window shows the document but "hold for authentication" notice appears. If I reload the print in that window, I do not get prompted to enter any identification; the print just remains paused.

What I have done in response to the many suggested solutions in Apple support:

1] "reset" both printer systems at both the Mini and MacBook.

2] Removed and re-added printer at both systems.

3] Rebooted. But have not done in to safe mode.

4] Set Printer Sharing "ON" and selected "everyone:Can Print."

One thread here suggested adding a specific "user" through the Print Sharing window. When I click the "+" sign, it just gives me a long column of groups from my Contacts. Not sure what to do with that.

This issue has been exhaustively covered in Apple Support, but I have not seen any of those threads that concluded with a solution.

Summary: This began coincident with the upgrade from Monterey to Sequoia with no prior difficulties with printing from the remote MacBook. The printer functions normally when printing from the USB connected M1 Mac Mini.

Any thoughts? Thank you.
