Apache POI setPrintArea to A4 page size

问题

I'm working with the Apache POI API to generate .xls files, and I want to set the printArea of my file.

I know there is a funcion called setPrintArea() but this one receive as parameters start and end row and column of my print area.

I want to know, if there is a way to set my print area for each sheet with the size of an A4 paper (210mmx290mm)

Thanks.

For each Sheet in the workbook, get its PrintSetup object and call setPaperSize on it, passing the appropriate PrintSetup constant: A4_PAPERSIZE.

mySheet.getPrintSetup().setPaperSize(PrintSetup.A4_PAPERSIZE);
