Just create a bookmark called paper jira and set the the following code content as target: paper-jira.min.js
Paper Jira is a bookmarklet that can be used to print out userstories from within Jira. This is wonderful if you want to work with a physical scrum board even though your Product Owner prepares the stories in Jira.
It can be used on a either the detail view of a story (example) or an entire list of userstories (list example).
You might want to change some of the settings to your need.
