The .printername propertity is not something your set but rather it would be used to retreive the name of the printer the is set. You may use it to make a comparison with the selected printer to confirm that the user wants to use the same printer that is already set:

SET PRINTER TO NAME GETPRINTER()
myPrinter =SET("Printer",3)
IF myPrinter <> oRep.PrinterName
   ** SET the printer correctly
ENDIF
