I have an intranet application that has a few "printer friendly" buttons on pages users were expected to print, and I really would like to get rid of them. The previous designers didn't know what they were doing and the print buttons are a particularly ugly example. In my opinion Printer Friendly buttons just make the layout that much more erratic (they're on very few pages), the print version as-is looks nothing like the normal version, and I would really rather print by CSS.
In fact the default print settings in most browsers actually make my pages look 90% okay in print, all the print button is doing is removing the navigation buttons and all styles; this has the effect of destroying the user interface and forcing the use of the back button.
So is there a reason I should keep these? I hate to just do it for "consistency's" sake, because the behavior is NOT consistent. However I do want my users to be able to print, and I don't want them to think that without those buttons the printout won't work or that it will be ugly. Do people even use these buttons? Is there any research on them? Any recommendations are welcome. I have barely seen "Printer Friendly" buttons on webpages (outside of news articles) in years, I was hoping they had fallen out of favor.
