Best practices for print functionality?

I am attempting to find the best practices to implement printing functionality. I am aware of the options for a paid plug-in as well as using the page browser, however, am looking for other methods that may be possible.

Some requirements for the print functionality are that:

• User has capabilities of printing data. When the user clicks on the print link, the system shall:
  • Enable the Print button.
  • User shall be able to Print all records on the page by clicking the print link.
