I am currently tying to add classes to the datatables csv, print, and pdf buttons.

During inspection of the default class names they have, i ran into the following differences.

The print button does not have the class name buttons-html5 like the csv and pdf buttons do.

buttons.print.js line 83 only has the classname buttons-print and not the buttons-html5

Is this something that was done on purpose?

If not, I wanted to suggest they be consistent during creation to avoid css styling differences? maybe an update in a future build? I was not sure if I should bring this up but felt like its better to mention if there was a need to update?
