I use the famous A list apart article (CSS Design: Going to Print) and this article when I need to make a printable version of a page. here are some common tags, but a lot depends on the css model (as well as container padding and margins) you are using:
body {
background: white;
font-size: 12pt;
}
#menu {
display: none;
}
#wrapper, #content {
width: auto;
margin: 0 5%;
padding: 0;
border: 0;
float: none !important;
color: black;
background: transparent none;
}
div#content {
margin-left: 10%;
padding-top: 1em;
border-top: 1px solid #930;
}
div#mast {
margin-bottom: -8px;
}
div#mast img {
vertical-align: bottom;
}
a:link, a:visited {
color: #520;
background: transparent;
font-weight: bold;
text-decoration: underline;
}
#content a:link:after, #content a:visited:after {
content: " (" attr(href) ") ";
font-size: 90%;
}
#content a[href^="/"]:after {
content: " (http://www.alistapart.com" attr(href) ") ";
}
