How to convert a web page into a PDF?

I found wkhtmltopdf project, which seems to do the trick. It's command line, so there is a bit of a learning curve, but not too bad.

Specifically to convert a web page, open a command window in the directory where wkhtmltopdf was installed and execute the following:

wkhtmltopdf.exe http://www.yourpage.com/index.htm c:\misc\cnn.pdf

The application has a ridiculous amount of options designed to tweak the output as needed, but the defaults give a pretty good result.

CutePDF writer uses GhostScript for text processing and then ps2pdf to create searchable PDFs of web pages. This will of course not work if the text on the page is an image to start out with.

What's the problem with Print to PDF solutions? I've two virtual printers installed in my system: PDF Creator & Virtual Printer from Adobe Acrobat X. Both work fine. I can search text in generated PDFs easily as long as my PDF viewer has OCR capabilities (which is common these days).
If you are thinking about creating something like text and word document, you can't. Its limitation of PDF format or says its how PDF format work. Due to this, we can embed fonts etc. in this format without any dependency to make it universal.
And, I don't think wkhtmltopdf project can generate a PDF file in which text can be searched without using OCR technology (because it'll violate PDF specification).

I use Adobe Acrobat 8 Professional (current version is Adobe Acrobat X). It has a menu option File... Create PDF... From Web Page... which asks me for a URL, then it downloads the page at the URL as a PDF file, with searchable text. It will also convert pages linked to from that page, recursively. You can end up with many HTML pages in one multi-page PDF file, with inter-page links preserved.

For some web pages, Acrobat Create PDF gets the formatting wrong. In that case I fall back to the Adobe PDF 8.0 printer driver which Acrobat 8 Professional installed on my system. It is very good at giving me a PDF equivalent of the web page I'm looking at, with searchable text.

Adobe Acrobat 8 Professional is not free software. It's fully-priced proprietary software. However IMHO it deserves as much a place in every knowledge worker's computer as does Microsoft Office. And, you didn't specify that you insisted on a free software way to convert a Web page into searchable PDF.
