When Button or Spacebar Pressed, Printing Stops
When guest hits start button, picture that is printing from previous guest stops printing and only part of picture prints.
The windows print spooler shut down without warning or notification. Restarted computer. Found guests photo in file and reprinted.
Window print spooler can also shutdown because of the spacebar press. So if you are using a USB button, change it to emulate the Enter key instead of the spacebar.
