I have a "print this post" link below my byline on each post and am using the standard print function included in the theme (I set it up in the kicker/byline/footer section of the theme's options).

The problem is that every time I print a post, the text comes out of the printer in a one-inch strip along the left hand side of the paper; in other words, the text does not fill the paper.

Does anyone know why I'm getting this weird behavior when I click the print this post link? Shouldn't the link format the text correctly and send it to my printer so that it fits nicely on the page and not in a one-inch strip along the side of the page?

You can see what I'm talking about by visiting my blog at http://abroadinspain.com and trying to print any post using the print function below the byline.

Thanks in advance for your help!

You could use the %wp-print and the wp-print plugin. see the description at ATO-Post/Page Info Items

The page is a big table and it looks like the print code you are using is defaulting to the width of the left column

This is corrected in newer versions. In you 3.2 replace the PRINT section in style.css with this:

/* ------------------------------------------------------------------
---------- PRINT STYLE ----------------------------------------------
------------------------------------------------------------------ */

@media print {

    body { 
        background: white; 
        color: black; 
        margin: 0; 
        font-size: 10pt !important; 
        font-family: arial, sans-serif; 
        }

    div.post-footer {
        line-height: normal !important;
        color: #555 !important;
        font-size: 9pt !important;
        }

    a:link, 
    a:visited, 
    a:active,
    a:hover {
        text-decoration: underline !important; 
        color: #000;
        }
        
    h2 {
        color: #000; 
        font-size: 14pt !important; 
        font-weight: normal !important;
        }
        
    h3 {
        color: #000; 
        font-size: 12pt !important; 
        }
        
    #header, 
    #footer, 
    .colone, 
    .colthree,
    .navigation, 
    .navigation-top,
    .navigation-middle,
    .navigation-bottom,
    .wp-pagenavi-navigation, 
    #comment, 
    #respond,
    .remove-for-print {
        display: none;
        }

    td#left, td#right {
        width: 0;
        }

    td#middle {
        width: 100%;
        }

    /* 4 hacks for display:none for td#left and td#right for all all browsers except IE. */

    *:lang(en) td#left{
        display: none;
        }
        
    *:lang(en) td#right{
        display: none;
        }

    td#left:empty {
        display: none;
        }

    td#right:empty {
        display: none;
        }

}    

Thank's Flynn! That code did the trick!

Thanks again!
