Question

我对python和编程很新，所以请原谅任何天真。

我想将此网页转换为pdf：http://www.ukmt-resources.org.uk/JMC16.html

我通过终端在我的Mac上使用pdfkit和wkhtmltopdf。它完成了这项工作，但生成的pdf是无用的，因为pdf最终看起来像this

是否有任何方法/是否有任何可以添加的设置将其转换为某种形式的可读格式，其中每页有合理数量的问题？

感谢您的帮助！

标记单个图像。也许您需要预处理页面，在处理之前将其分解为多个页面。

您必须决定页面放置，因为很难让PDF生成器决定如何将没有页面（HTML）的内容分解为页面（PDF）。
