Old reliable double-side printer selectable disappeared.

[Jotra1]

Something changed in 2024. My ability to select double-side print has disappeared from the printing menu.  It's been an option from the time I bought this old, but reliable printer.
Where did it go?

I downloaded any and all current HP info I could find, but the only time I see double-side print option (manual verse automatic) is for MS Word documents and there's no double-side selectable for PDF files.

Note: when I open a MS Word document to print two-sided I can then open a PDF, but it only allows manual 2 sided printing.

Why take it away when it's what makes the printer a meaningful small business tool.

Never mind resolved on my own. 

I downloaded all recent HP SW versions/patches and then powered off printer, removed printer from devices, reconnected printer and then powered up and shazam the 2-side printer option was back on the printer menu!
