If switched on, automatically inserted blank pages are being exported to pdf file. This is best if you are printing the pdf file double-sided. Example: In a book a chapter paragraph style is set to always start with an odd numbered page. The previous chapter ends on an odd page. %PRODUCTNAME inserts an even numbered blank page. This option controls whether to export that even numbered page or not.
如果打开，则会将自动插入的空白页导出到 pdf 文件。对 pdf 文件执行双面打印时，此方法为最佳选择。示例：在某本书中，章节段落样式被设置为始终以奇数页开始。如果前一章在奇数页结束，则 %PRODUCTNAME 会插入一个偶数空白页。此选项控制是否导出该偶数页。
