11、POI打印功能
11.1、常用模块形式：
1 HSSFPrintSetup printSetup = sheet.getPrintSetup(); 2 printSetup.setVResolution((short) 600); //打印质量600点 3 printSetup.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE); //A4纸张打印 4 printSetup.setLandscape(true); //横向打印
11.2、常用参数设置方法
1、页面设置
1.1、方向：
纵向(T)：HSSFPrintSetup#setLandscape(false); [默认状态]
横向(L)：HSSFPrintSetup#setLandscape(true);
1.2、缩放：
缩放比例(A)：HSSFPrintSetup#setScale((short) 100); [默认状态]
调整(F): 页宽 HSSFPrintSetup#setFitWidth((short) 1);
页高 HSSFPrintSetup#setFitHeight((short) 0);
1.3、纸张大小(Z)：HSSFPrintSetup#setPageSize(HSSFPrintSetup.LETTER_PAPERSIZE);
纸张大小定义说明：
public static final short LETTER_PAPERSIZE = 1;
public static final short LEGAL_PAPERSIZE = 5;
public static final short EXECUTIVE_PAPERSIZE = 7;
public static final short A4_PAPERSIZE = 9;
public static final short A5_PAPERSIZE = 11;
public static final short ENVELOPE_10_PAPERSIZE = 20;
public static final short ENVELOPE_DL_PAPERSIZE = 27;
public static final short ENVELOPE_CS_PAPERSIZE = 28;
public static final short ENVELOPE_MONARCH_PAPERSIZE = 37;
1.4、打印质量(Q): HSSFPrintSetup#setVResolution((short) 300);
1.5、起始页码(R): HSSFPrintSetup#setPageStrart((short) 0); [默认状态]
2、页面距
2.1、上(T): HSSFSheet#setMargin(HSSFSheet.TopMargin,(short) 0.6);
2.2、下(B): HSSFSheet#setMargin(HSSFSheet.BottomMargin,(short) 0.6);
2.3、左(L): HSSFSheet#setMargin(HSSFSheet.LeftMargin,(short) 0.6);
2.4、右(R): HSSFSheet#setMargin(HSSFSheet.RightMargin,(short) 0.2);
2.5、页眉(A): HSSFPrintSetup#setHeaderMargin((double) 0.2);
2.6、页脚(F): HSSFPrintSetup#setFooterMargin((double) 0.6);
2.7、居中对齐方式: 水平(Z) HSSFSheet#setHorizontallyCenter(false);
垂直(V) HSSFSheet#setVerticallyCenter(false);
3、页眉/页脚
3.1、页眉：HSSFHeader#setLeft（HSSFHeader.date();
说明：首先获得HSSFHeader对象，确定页眉的显示位置(如：左边显示页眉HSSFHeader#setLeft(显示内容))
可用：HSSFHeader#setLeft,setCenter,setRight
3.2、页脚: HSSFFotter#setLeft（HSSFFotter.page()+”/”+HSSFFotter.numPages()）
说明同页眉
4、工作表
4.1、打印区域
HSSFWorkbook#setPrintArea((int) sheetIndex, (int) startColumn, (int) endColumn, (int) startRow, (int) endRow);
参数说明：
sheetIndex–从0开始的sheet的索引编号
startColumn-打印区域的开始列号
endColumn- 打印区域的结束列号
startRow-打印区域的开始行号
endRow- 打印区域的结束行号
4.2、打印标题
HSSFWorkbook#setRepeatingRowsAndColumns((int) sheetIndex, (int) startColumn, (int) endColumn, (int) startRow, (int) endRow);
参数说明同上。
使用说明：仅仅设置左端标题列：workbook.setRepeatingRowsAndColumns(0,0,1,-1,-1);
仅仅设置顶端标题行：workbook.setRepeatingRowsAndColumns(0,-1,-1,0,4);
同时设置左端和顶端标题：workbook.setRepeatingRowsAndColumns(0,-1,-1,-1,-1);
4.3、打印
网格线 (G)：HSSFSheet#setPrintGridlines(false);
单色打印(B)HSSFPrintSetup#setNoColor(false);
按草稿方式（Q）：HSSFPrintSetup#setDraft(false)；
行号列标(L):
批注(M):
错误单元格打印为(E):
4.4、打印顺序
HSSFPrintSetup#setLeftToRight(false)；
11.3、程序示例:
