打印设置主要包括方向设置、缩放、纸张设置、页边距等。NPOI 1.2支持大部分打印属性,能够让你轻松满足客户的打印需要。
首先是方向设置,Excel支持两种页面方向,即纵向和横向。
在NPOI中如何设置呢?你可以通过HSSFSheet.PrintSetup.Landscape来设置,Landscape是布尔类型的,在英语中是横向的意思。如果Landscape等于true,则表示页面方向为横向;否则为纵向。
接着是缩放设置,
这里的缩放比例对应于HSSFSheet.PrintSetup.Scale,而页宽和页高分别对应于 HSSFSheet.PrintSetup.FitWidth和HSSFSheet.PrintSetup.FitHeight。要注意的是,这里的 PrintSetup.Scale应该被设置为0-100之间的值,而不是小数。
接下来就是纸张设置了,对应于HSSFSheet.PrintSetup.PaperSize,但这里的PaperSize并不是随便设置的,而是由一些固定的值决定的,具体的值与对应的纸张如下表所示:

HSSFSheet下面定义了一些xxxx_PAPERSIZE的常量,但都是非常常用的纸张大小,如果满足不了你的需要,可以根据上表自己给PaperSize属性赋值。所以,如果你要设置纸张大小可以用这样的代码:
HSSFSheet.PrintSetup.PaperSize=HSSFSheet.A4_PAPERSIZE;
或
HSSFSheet.PrintSetup.PaperSize=9; (A4 210*297mm)
再下来就是打印的起始页码,它对应于HSSFSheet.PrintSetup.PageStart和 HSSFSheet.PrintSetup.UsePage,如果UsePage=false,那么就相当于“自动”,这时PageStart不起作用; 如果UsePage=true,PageStart才会起作用。所以在设置PageStart之前,必须先把UsePage设置为true。
“打印”栏中的“网格线”设置对应于HSSFSheet.IsPrintGridlines,请注意,这里不是 HSSFSheet.PrintSetup下面,所以别搞混了。这里之所以不隶属于PrintSetup是由底层存储该信息的record决定的,底层是 把IsGridsPrinted放在GridsetRecord里面的,而不是PrintSetupRecord里面的,尽管界面上是放在一起的。另外还 有一个HSSFSheet.IsGridsPrinted属性,这个属性对应于底层的gridset Record,但这个record是保留的,从微软的文档显示没有任何意义,所以这个属性请不要去设置。
“单色打印”则对应于HSSFSheet.PrintSetup.NoColors,这是布尔类型的,值为true时,表示单色打印。
“草稿品质”对应于HSSFSheet.PrintSetup.IsDraft,也是布尔类型的,值为true时,表示用草稿品质打印。
这里的打印顺序是由HSSFSheet.PrintSetup.LeftToRight决定的,它是布尔类型的,当为true时,则表示“先行后列”;如果是false,则表示“先列后行”。
在NPOI 1.2中,“行号列标”、“批注”和“错误单元格打印为”、“页边距”暂不支持,将在以后的版本中支持。
