The most common print button I run into is on airline web sites (for 
printing boarding passes).  Of those, the ones I've looked into seem to 
be using frames and the print button just calls window.print() on the 
right frame.  That frame is already printer-friendly enough.

Come to think of it, airline boarding passes are the only case in which 
I print things from the web using either print buttons or the browser's 
"print" functionality.  Are there other common printing use cases?  What 
are they?
