CMS Made Simple Forums

I'm building a site from a clean CMSMS-installation (latest version). Added Calendar and News -modules, and added a detailspage for them. How do I make use of the Printing module (especially PDF-generation) when viewing an item?

Site can be viewed at: http://pym.se/aciw

Code I'm using:
{cms_module module='Calendar' inline=0 detailpage="kalender" first_day_of_week='0' table_id='big' lang="sv_SE"}

And:
{print showbutton=true script=true}
{print  showbutton=true  pdf=true}

Thanks in advance!
