Feature request: Divide the setting of hibernation time into two: standby and printing.

I can set different hibernation time values in the standby and print states.

For example, 2 minutes in the standby state and continuously open the screen in the print state, the PandaTouch will then turn off the screen 2 minutes after printing is complete.

No file or test is named. Start by locating the existing hibernation-time setting and the code handling standby and printing states. Done means standby and printing each have separate screen timeout values, including keeping the screen continuously open while printing and applying the standby timeout after printing ends.
