Why do you need to change the wifi on the printer. The last time I replaced the router I used the same network name & password. Had to reboot the printer to make everything work but was fine. (really odd that I could open the printer's web page but not print)

I just replaced a magenta printer cartridge and all color prints come out with that color mixed in. Will figure it out after my road trip.
