I have an HP P3015 printer. It has a network jack on the back of it and I want to network it for my office. I don't have the CD for it anymore. I plugged it into a usb port of my computer and it installed correctly and works just fine with usb. How do I setup this printer so users can install it over the network? I can't seem to find the manuals online or the correct software. Can someone give me some help?
