本文介绍了如何利用SumatraPDF的命令行选项对PDF文件进行方向调整、缩放处理，确保打印时不出现内容超出，并通过pypdf库编辑PDF添加边框。还演示了如何根据页面尺寸自动选择打印方向并设置打印机参数。

SumatraPDF 文档
https://www.sumatrapdfreader.org/docs/Command-line-arguments
⽆边框 noscale/缩⼩到合适⼤⼩（默认）shrink/合适⼤⼩ fit/compat 兼容
# 分为 Portrait (纵向)和 Landscape (横向)两类

# 如果打印的内容超出了打印纸，可以先用 pypdf 库编辑pdf文件，给每一页四周加长，相当于加了一个边框，再打印时，自适应就不会内容超出
