JeffreyCox you ROCK! I've been battling this won't-print-in-color (among several other issues with this printer) and had just re-installed the printer on Monday, so I was by no means going to deal with that again, but I followed your VERY simple instructions to use Windows10 functionality by going to Start -> Printers & scanners, then I chose the hp 3830, clicked "Remove Device", then clicked the button/link to "add a device", and chose the printer again, VIOLA! COLOR PRINTING! PHEW! The whole thing took maybe 90 seconds.
THANK YOU!!!!!!!!!!!!!!! This was soooooo much more helpful than the typical support team response (power down, unplug from wall, uninstall, reinstall, blah blah blah . . . total CRAP which never fixes anything.) THANKS AGAIN!!!
