I am in a dense wifi environment. Because of this the sys admin will only authorize Ethernet connected printers. It seems as if all of the printers these days have wifi capabilities built in. I picked up a HP printer to see if the wifi could be tuned off so my sys admin would approve it. Even with the wifi turned off in the settings the wifi radio was still active. He will not authorize it and I had to return it. I need a printer that has no wifi, the wifi "radio" can be turned off either by software settings or physically "unplugged".
