Often Papercut will crash on your PC, here is how to get it back if it does so-
1. Go on to your physical hard drive
Do this by right-clicking on the windows icon in the bottom left-hand side of your screen then pressing 'Run' and type "c:" into the prompted box.
and then type "C:" into the prompted box.
Once at this stage press 'OK'
2. Re-running Papercut
After accessing your harddrive go into the 'Cache' folder.
Then go into the newest version of Papercut
Finally, double click on 'pc-client'
Following this Papercut will then be reopened and you will then be able to print.
