Best Third Button Placement in Website

I'm currently redesigning a website for internal staffs in a company, I have a case that users are filled in a form and can go to the next page the form and then there would be a print button in the same page. But the thing is I have then 3 buttons, there are "finish", "print" and "back". I just wondering where the best placement should be if there are 3 buttons in the same page. Users need to do the "print" first and then they could be "finish". At first I think I would place the print with icon and place it above the form, but that would be another research, as I don't really want to change their behavior that much (by placing print above the form).

the page before "print" button the page before "print" button

my idea because they need to do "print" first, and then "finish". "finish" button would be disabled when user haven't clicked on "print" button enter image description here

"print" button is left aligned so that the "finish" & "back" button stay at the same spot as "prev" & "next" button. enter image description here
