Yes, I did go to /Library/Preferences but the file does not exist. I also looked through the whole Library folder for anything that may relate to the Printer, my Lexmark printer or Safari.
When I opened a doscument in Preview it defaulted to 97%. When I make changes and save as a preset the changes are not saved. When I go to use the saved preset it has the system default values not my choices.
TextEdit does have the same selection layout.
With Safari when you print a web page with the 150% scale it can't print correctly and words are missing of text documents, if you print in haste and don't manually change the 150% setting you need to reprint it again correctly which is a real pain and a waste.
