I installed Arch recently and am lost on setting up the printer (hp envy photo 7855). the printer wiki says that the page needs to be updated. Could someone help?

I installed hplip (and that installed cups and other stuff) and I installed usbutils to get lsusb. I was having difficulties getting lsusb to detect the printer... until I discovered it doesn't really plug-n-play. The printer needs to be plugged in from power-on.
