发票批量排版打印在A4纸75%大小

wwwwtw · 发表于 2026-6-23 10:13

白嫖好多年了，因工作需要，找了一圈没有找到合适的工具，一般的工具都是打印在A4的上半部和整页，我想打印成第三种样式，方便打胶粘贴等，未找到相关工具。

用AI写了个powershell，达到了第三种样式的目的，但是需要借助SumatraPDF.exe,可自行去官网下载，（此处使用SumatraPDF-3.6.1-64.exe做演示，第八行请自行更换SumatraPDF的路径）

AI生成，自行检测代码安全性。

使用方法：
配置好SumatraPDF的路径，将以下代码用记事本保存为【xxx.ps1】格式，初次运行可能会提示什么不受信任的powershell脚本，很简单，自行解决，打开后会弹出pdf选择界面，选择你需要打印的pdf发票（可多选），会自动排版打印成上图的第三种格式，有需要的自取。

附SumatraPDF-3.6.1-64.exe链接，或自行去官网下载。

我个人对比了一下，觉得最方便的A4纸打印发票还是2345看图王11往后的版本，其中附带的pdf发票打印功能，能设置在一张A4纸打印两张甚至四张发票，还是相当方便。当然这涉及三个问题，一是2345看图王得用去广告版，二是看图王的版本必须是11.3往后，三是只适应A4纸而不是A5纸打印发票。个人意见，仅供参考。

打印，选实际大小，居中。不能实现吗？

正解，哪个能打开pdf的应该都能实现

word文档中贴图，拖动大小不就可以一页打多张吗

我们单位发票打印都是A5

应该是方便财务装订吧
