Can't get the 3d printer to print
We have a Prusa 3d printer and it was working, but then the computer decided to do a systems upgrade without any notice, thereby causing the 3d printer to stop. We couldn't get it to restart and now we can't even get it to print anything new at all. The SD card works, but would rather not use it since our computer does not have an SD port to download files. Any suggestions as to what is going on and how to fix it would be greatly appreciated. We tried looking online for answers but can't seem to find anything that helps.
