Is it possible to hide standard buttons from a particular role？

The print and new buttons? Not without DOM manipulation I think. Something on the actions drop down? Yeah - you can hide those by editing the form, or by moving them to a button and then hiding via workflow.

Check if is possible via workflow

Yup, this looks like DOM manipulation/a bit of sweet jQuery to hit the trick, really not sure if standard is available!

Thank you so much! 😄 I'll try via workflow first!
