Just link the text or image people will use for downloading a specific page/url:
http://impdf.com?url=impdf.com

for example:

<a href="http://impdf.com?url=impdf.com">download this page as PDF</a>

 How to use on your server?
 

Synopsis (the first -O <filename> is wget's own output file option): 

 wget -O impdf.pdf "impdf.com?url=impdf.com&-O=Landscape&--header-left=hello"


 General Options:
 You can mix-and-match the underneath options to customize the pdf to your needs.

For example, if you want a landscaped PDF you add -O=Landscape or --orientation=Landscape and if you want to add a header with text aligned to the left you would use --header-left=hiYou can also alter the default filename by providing the --filename=ot.pdf option.
These three options combined in one text link would look like this:
 

<a href="http://impdf.com?url=impdf.com&-O=Landscape&--header-left=hi&--filename=ot.pdf">pdf</a> 

Notice that in the above example the ampersand "&" sign separates each option, and the separating character for a parameter is an equals "=" sign. You will need to url escape any reserved url characters for option values.

Specifying A Proxy:
By default proxy information will be read from the environment variables: proxy,
all_proxy and http_proxy, proxy options can also by specified with the -p switch

<type> := "http://" | "socks5://"
<serif> := <username> (":" <password>)? "@"
<proxy> := "None" | <type>? <sering>? <host> (":" <port>)?

Here are some examples (In case you are unfamiliar with the BNF):

http://user:password@myproxyserver:8080
socks5://myproxyserver
None

Footers And Headers:
Headers and footers can be added to the document by the --header-* and --footer* arguments respectfully. In header and footer text string supplied to e.g. --header-left, the following variables will be substituted.
 

* [page] Replaced by the number of the pages currently being printed
* [frompage] Replaced by the number of the first page to be printed
* [topage] Replaced by the number of the last page to be printed
* [webpage] Replaced by the URL of the page being printed
* [section] Replaced by the name of the current section
* [subsection] Replaced by the name of the current subsection
* [date] Replaced by the current date in system local format
* [time] Replaced by the current time in system local format

As an example specifying --header-right "Page [page] of [toPage]", will result in the text "Page x of y" where x is the number of the current page and y is the number of the last page, to appear in the upper left corner in the document.

Headers and footers can also be supplied with HTML documents. As an example one could specify "--header-html header.html", and use the following content in header.html:

<html><head><script>
function subst()
{
    var vars={};
    var x=document.location.search.substring(1).split('&');
    for(var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
    var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
    for(var i in x) {
        var y = document.getElementsByClassName(x[i]);
        for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
    }
}
</script></head><body style="border:0; margin: 0;" onload="subst()">
<table style="border-bottom: 1px solid black; width: 100%">
  <tr>
    <td class="section"></td>
      <td style="text-align:right">
        Page <span class="page"></span> of <span class="topage"></span>
      </td>
    </tr>
  </table>
</body></html>

As can be seen from the example, the arguments are sent to the header/footer html documents in get fashion.

Outlines:
imhtmltopdf has support for PDF outlines also known as bookmarks, this can be enabled by specifying the --outline switch. The outlines are generated based on the <h?> tags, for a in-depth description of how this is done see the "Table Of Contest" section.

The outline tree can sometimes be very deep, if the <h?> tags where spread to generous in the HTML document. The --outline-depth switch can be used to bound this.
