Using PDFKit as a middleware allows you to render all pages as a pdf. But it can be done for a specific action by specifying the rendering format. For that you need to register mime type for version 0.3.3 and i think its fixed in the newer version. And here is a snippet.

format.pdf {
html_text = render_to_string(:layout => false, :action => "show.pdf.erb")
pdf_output = PDFKit.new(html_text, :print_media_type => true)
pdf_output.stylesheets << Rails.root + "public/stylesheets/print.css"
send_data(pdf_output.to_pdf, :filename => "filename.pdf", :type =>'application/pdf')
}

I have used show.pdf.erb as the view template which is similar to show.html.erb but without irrelevant elements and print_media_type is set to true to use different style-sheet and used Rails.root instead of RAILS_ROOT for rails 3.

hope it helps :)
