Change Js Link/behavior To Existing Jquery Script

Hi,

I have a floating side link that pops a javascript ajax form.

onclick needs to use an existing jquery print from iframe script instead of popping the current form.
Script is located here (demo & download):

Printing web pages & a new jQuery print plugin

The jquery script installs easy, but I don’t know how to alter the current floating link to get rid of the ajax form and trigger the jquery print from iframe instead.
