Printer Friendly Contact Record
If you use Drupal, I'd recommend setting up a view that lays out the bits you want for your print-friendly data screen, and then use the Drupal print module to give you the print-friendly and/or pdf-generated versions.

The print module can actually generate both print-friendly and pdf-generated versions of any page (via a url trick, prefix with "print/"), i.e. you can use a url like this:

/print/civicrm/contact/view?reset=1&amp;cid=yourcontactid


but they probably won't look very nice. You can do some customziations via the print.css file of your theme.

It's probably harder than you think, less useful, and not a good idea most of the time as noted in the comments above.
