Inkjet All in One 6978 will now print color in HP program to find problems. It will not print color in any program outside HP. HP thinks everything is OK. No, it's not. Printer is out of warranty, but this is a weird problem. HP does not see that no other program prints color but HP does.
Here is my reply: I did all you asked. It printed Color in HP. Outside HP, it printed B&W ... until I printed a Publisher file. It was in Color. Puzzled I went back and tried to print another photo. It print B&W. THEN, I noticed, in Win10, when you print a photo, the Win10 program has a button at the top, saying "Allow this program to change the way it prints" and it was checked OK. For the hell of it, I clicked the button to turn off the option, and the photo NOW printed in Color! So it seem my problem was probably Win10's photo print program turn on an absurd button to "alter" the printing, in the case from Color to B&W! Everything seems to be working fine now.
