Unanswered Printer shutdown during night!!!

I got up at 4am to check on a long run. I found the printer shutdown with nozzle over print as if it just stopped.
The computer as displaying the sign in screen. When I entered the password it said Microsoft had added up dates. Now here's the thing, only the printer program was selected. Foxfire was not. My internet access is over the air, that is not wired. It comes in over Verizon's cell system. It looks like they can get in even when Foxfire is off.
This could screw up any long print. Any suggestions? Frank

 

turn off autoupdate or select to download manually, check your power settings and put them at high performance (full cpu, fan, backlight, hard drive set them to never power down, turn off the screen saver, edit property's in device manager for the usb and uncheck box for green mode/energy efficient/power save mode ect... that allows the pc to power down the usb ports.
