Print postal address labels with cck and views templates

hi,
i just thought of sharing a little snippet on how to print postal labels with drupal out of addresses.
using cck and views templates, i created a custom function in themes/mytheme/template.php corresponding to my view (named label2).
then, by customizing print.css, i can only print the labels. note the "div style="page-break-after:always" to create page breaks with css2.
