Thanks for your replies, which prompted me to play around some more. What I have found is it is not possible, as it is in PPENG, to press PrtScn from the simulator in PEP and automatically a Pronto folder is created on the C: drive with the screenshot images labelled in sequence. In PEP no such folder is created. From the PEP simulator "PrtScn" by itself copies the entire computer screen to the clipboard, ALT+PrtScn copies both the simulator and its contents as one image to the clipboard and, what worked for me, pressing CTRL+PrtScn once in the simulator sends the screenshot only to the clipboard to be used as desired.
