For a long time my printer was ghost printing, ghost faxing, ghost copying, and ghost scanning. But other than that it worked just fine, via wifi. I recently got a new Comcast Xfinity modem, and the technician who installed it was unable to make my printer work. I reinstalled the printer software, and it shows up when you look in control panel, and the HP Solution Center shows everything should be OK, but when I try to print, an error message says I don't have a printer installed. When I click on install new printer, it says, cannot access install new printer. F-ing HP won't take a call on this ancient 5-year old printer so I am asking here. Ironically, I can still scan just fine. Thanks.
Are you using a dual band router? Yes and I've named both bands.
When I reinstalled the software, It prompted me to plug in the USB, then at some point to unplug it. I did that, but it didn't find the printer. I'll try what you said I guess, and let you know how it turns out. Thanks.
