Not finding Bluetooth

[Bluebell58]

I'm running an Apple iMac using OS 15.6.1 (Latest OS). It was Bluetooth connected to my HP Deskjet 2810 all-in-one-printer.  Now it won't connect. I've powered both the iMac and the printer OFF and back on after a few minutes many times with no success. The blue Bluetooth LED on the printer blinks when first powered on, then after a few seconds turns into a steady blue.

However the list of available Bluetooth devices showing on my iMac, does not include the printer.

So I am unable to select the printer (showing) in my System set-up pane.

Any help appreciated.
