Thanks for your help. It's cleared now. As I described, the problem affected all other apps as well as Paint.Net. So I zapped everything relating to my printed and re-installed. The problem was still there. But I had read several internet 'solutions' to the problem. I applied them all. At the end, it was fixed. I don't know which 'solution' fixed it.

You don't state which application I should be in to click "Options", then "Printer Properties". None of my applications, including Paint.NET, has such an option.

I have suddenly encountered a problem whereby I cannot print colour pictures. It affects all my software applications but is clearest when using Paint.Net. The problem. Whenever I try to print a picture, it always comes out in black and white. I have tried Photoshop and Faststone Image Viewer in particular. But Paint.Net gives me the clearest clues. I open a colour picture in Paint.Net, and choose File > Print. My Print dialogue contains 'printers' which include Adobe PDF, Microsoft PDF, SnagIt, OneNote - all of which show a coloured print preview. But when I want to send it to a real printer (HP ENVY 4520 Series) the preview changes to B&W. The picture then prints in B&W. This has only just started happening, today, and I haven't changed any application. Test prints from the printer come out in perfect colour. Can anyone understand why?
