You could try styling the anchor to look like a button.I just copied the various dijit styles of the button to the anchor.
a.esriPrintout
{
text-decoration: none;
font-weight: bold;
display: inline-block;
color: #421B14;
width: 160px; /** this was set in the demo page **/
cursor: pointer;
margin: 0;
line-height: normal;
vertical-align: middle;
white-space: nowrap;
text-align: center;
/** This is where the button look starts to take shape **/
border: 1px solid #DEDEDE;
border-bottom: 1px solid #DEDEDE;
padding: 0.1em 0.2em 0.2em 0.2em;
background: white url(images/buttonEnabled.png) repeat-x top left;
}
a.esriPrintout:hover
{
color: #5EC5E6; /** I just picked something that would stand out **/
}
Luckily they gave the anchor a class that could be reached pretty easily without funky css selectors.
