skp to eps conversion is used for the purpose of exporting SketchUp content (.skp) to PostScript format (.eps), typically for the purpose of printing on special printers or to act as an exchange format for transfer between different software.
SketchUp does not support PostScript by default, so you will either need a plugin that adds this function, use a virtual PostScript printer or some 3rd party solution that supports both SKP and EPS formats.
