Cards can be printed from several places in JIRA, i.e. from each single issue, from Issue Navigato, from JIRA Agile board (whole sprints and columns) and from JIRA Core boards. After clicking the
Print Issue(s) option in any of these places you will be redirected to cards generated by the plugin. Now you can print cards using Print Cards option or download them as a PDF using Generate PDF option (available only on JIRA Server).
Before every cards generation you can select settings template that you want to use. Last used template is cached in your web browser so it's very easy to generate cards using your favourite template.
