Print posts category or tag as a formatted journal

You don’t have to use a specific plugin to achieve columns in print, you can modify how your layout looks when printing using the print CSS media query. You can learn more about this topic here.

In case of the WP Journal plugin to print 3 columns of text add this:

@media print {
    .cols3 {
        -webkit-column-count: 3;
        -webkit-column-gap: 20px;
        -webkit-column-rule: 1px solid silver;
        -moz-column-count: 3;
        -moz-column-gap: 20px;
        -moz-column-rule: 1px solid silver;
        column-count: 3;
        column-gap: 20px;
        column-rule: 1px solid #000;
    }
}
