iMac causing issues with HP printer (no issues with Windows PC)
We bought our HP Envy Pro 6430 printer a couple of weeks ago and installed it on our new iMac (2021). Does anyone know why it might be selectively replacing areas of color (white and purple in this image) with black? It’s not an issue with the printer because it prints as it should form our old HP desktop running on Windows 10. Perhaps related to the new iMac or MacOS incompatibility or a setting?

Here is our printout for comparison.

Any troubleshooting suggestions?
We’ve been through two lots of printer resets, printhead clean, and printhead alignment with HP support which unsurprisingly did nothing.
