My pro X451dw printer is not printing colour photos properly. The quality test and colour tests are perfect from the printer itself. I'm using HP ink. There seems to be nothing wrong with the printer printing the 4 colours properly. All my photos appear somewhat greyish-green in colour. It happened both from my MacBook Pro and from an HP Laptop. We are sending via wifi to the printer. Somehow, I'm wondering whether the photo information is being sent properly to the printer or whether it is being received properly from the printer.
