TXlsFile.PrintOptionsInitializedFromPrinter Property
If this property is false, then Excel has not read the printer options from the printer, and TExcelFile.PrintLandscape, TExcelFile.PrintPaperSize, TExcelFile.PrintScale, TExcelFile.PrintXResolution, TExcelFile.PrintYResolution and TExcelFile.PrintCopies will be ignored. This property will change automatically to true if you manually change any of the above properties.
You shouldn't have to set this property, as it is set automatically to true when you set the others like TExcelFile.PrintLandscape. But if you set it to true, it will not only set the print options to initialized, but also initialize all uninitialized properties like TExcelFile.PrintLandscape to default values.
