@dlc60 By 'print directly from the console on the printer', do you mean you are using a PanelDue or 12864 display? Neither should disconnect the web interface, so something is not quite right. Please post the Maestro firmware version (M115) and PanelDue (if that's what you're using) firmware version, and the DWC version.
If you're using a 12864, what menu system are you using?
