PDFCreator User Manual 'pdfcreator.exe /OptionsFile' Question

PDFCreator 1.2.0 (January 23, 2011) User Manual, page 14 of 52.  Would like to know what the 'little work around' is, mentioned in the hint for Windows Server installation.

/OptionsFile

Hint: with this parameter ( and a little work around) you can use more than one printer on a machine.)
