Hello Ian and welcome to the forum.
I assume we are talking about a USB attached printer?
How about using devices and printers in the control panel to remove the printer from your computer.
Check programs and features, also in the control panel and remove any associated drivers
Check Device manager and is there is still a reference to it there, right click and uninstall it along with associated drivers.
Unplug the printer from the computer.
Turn off your computer
Examine the printer make sure that it is on, and in an error free state, paper, ink, no flashing lights, etc.
Reboot your computer and plug it back in.
Give it a minute or two
What happens then?
