My children are going crazy with the printer apps on my printer, every day I someone has turned on a new app and printed a pile of comics, puzzles, coloring pages etc. How do I password protect or block all apps from being turned on in the first place? I still want my printer to be hooked up to the network for the convenience of printing from any computer in the house, but the apps are driving me crazy and costing me a fortune in paper and ink. Please help.
