假设应该为热敏打印机生成一个jasper报告。细节带可以是1行或200+行。
如何生成jasper报告，其高度适合行数，而不是最后打印空格？
答案 0 :(得分：2)
Set the pageHeight to just one row and then use
isIgnorePagination="true"
When isIgnorePagination is true the report will be generated in a single page.
Hence, if just one row, it will have the height of one row, if more rows it will not create new pages but generate a continues layout.
For example see: http://jasperreports.sourceforge.net/sample.reference/nopagebreak/
