public class EasyExcelPrintA3Example {
    public static void main(String[] args) {
        // 创建工作簿
        Workbook workbook = EasyExcel.write("output.xlsx").build().write().getWorkbook();
        // 获取第一个工作表
        Sheet sheet = workbook.getSheetAt(0);
        // 设置纸张大小为A3
        sheet.getPrintSetup().setPaperSize(PaperSize.A3);

        // 其他操作，例如写入数据等

        // 关闭工作簿
        workbook.close();
    }
}
