发票批量打印
发票批量打印工具2月12日更新：
更新内容：
1、纸张大小新增A5四版和A5两版（A5进纸方向为竖向）
2、增加打印预览功能（有个小bug，部分自定义纸张预览图与实际打印效果会不一致）
3、可选OFD格式打印（下载Spire.Pdf.dll，不下载则pdf和图片格式依旧可以正常打印）（单个OFD文件页面不超过3页）。
4、增加多版打印图片之间的间隙。
5、评论区反馈部分pdf打印机出现卡死，经测试是因为这些打印机调用了windows文件对话框保存pdf文件，由于软件使用了多线程，在打印子线程中调用模态对话框就会出现线程冲突，现修复Adobe PDF和Microsoft Print to PDF打印机出现的冲突；
其他打印机解决方式1:点击界面最下方：使用系统打印对话框进行打印 。
方式2：找到该打印机设置界面-打印机首选项-设置指定保存位置不弹出对话框（如果有）。
方式3：从打印预览界面进行打印。
方式4：更换虚拟打印机（论坛搜索的几款都还不错）。
6、应评论区需求增加同一发票打印两版在一张A4纸上的功能，使用方法：勾选‘复制页面*2’，设置纸张大小‘A4两版’。
7、文件列表中可按Delete键删减选中。
重复一遍：如果使用虚拟打印机推荐勾选合并页面（生成一个文件）。
1月16日更新：
可选A4三版 和自定义纸张大小打印
自定义纸张大小最多保留3个，超过3个最后添加的会覆盖最先添加的
1月12日更新：
可选A4 四版和A4 六版 打印
可选添加裁剪线
PDF/图片打印
文件路径传入方式：拖入文件或者文件夹，双击列表输入路径等。
虚拟打印机推荐合并页面（生成一个文件），否则不合并页面（打印机响应速度会快那么一点）
A5进纸方向为竖向：148mmX210mm(宽X高)
请先少量测试页面方向是否正确，设置是否生效，再批量打印。
64位，不支持win7

提个意见
A4两版 时候，上下部分分别 向上和向下靠齐 也就是两端缩进些
中间区域留白增加
会更好
支持楼主的分享精神， 2张发票合并页面打印，并不是选择合并页面，而是纸张大小选A4两版。还有2个问题，能不能自由删除添加进去序列的文件，和输出PDF版自己保存。 感谢，这个是神级需求啊，谢谢 有空用一下谢谢分享 省时省力，感谢 非常好，谢谢，收藏了
