The PList files are 'Setup Information' files. I have opened one and the contents should appear below. It seems to be something to do with printing as all 107 have the name of a printer and they are in alphabetical order starting with the one that is printed here:-
All I can gather from that is that you have a Ricoh Aficio Laser printer model BP20 which is not a lot of help to you. But as the files are in the Temp folder and seem to be small text files they are not doing any harm and will be cleared out regularly when you run CCleaner for example or Windows own clean up utility.
