compatibility problem with print module

Seems to be a small compatibility issue with the print module.

Regarding the option to "hide vertical tab components" when configuring the block, if the print module is installed then it creates another vertical tab option on node creation called "Printer, email and PDF versions" which is not available in the list of "vertical tab components" to hide and therefore cannot be hidden.

Being able to hide the vertical tabs is very useful if not essential when placing a block in a sidebar so I thought I should create an issue in case you were unaware of the problem.

For the time being I have hidden with CSS but its not ideal.
