Here are some ideas on how to view the task lines for printing.

You can filter your project start and finish dates. 

Filter by double-clicking on the start date/finish date title name in their column. You will see a key appear for you to filter the dates of the task. 

You can do the same with your resources column. 

View and un-view completed tasks. Go to your view drop-down menu in the top toolbar. There you will see the option to "Show complete task" in your gantter grid.
