Where are the Photoshop CS2 page setups stored?

By accident my Photoshop CS2 custom page setups for my Epson Stylus Pro
7600 inkjet printer got erased, so i want to replace the setups with
older, backup file(s) but I don't know which one(s) to replace.

In the Library > Printers > Epson > Preferences folder, three files out
of the seven files listed there are shown to have been modified today.

Which one(s) should I replace with the older files from another drive?

The files are that are shown to have been modified today are:

PrintSettings.xml

PageSettings.xml and

com.epson.ijprinter.SPro_7600_1.mp.plist.

I checked in Photoshop in the Help section, and typed "Page Setup",
"Preferences" and "Library", but of course the information I need isn't
listed there, because the Help section is as useless as ever.

Thanks.
