Position of print window

[LowieDelneste]

Idea: make it possible to set the position of the print window.

Possible implementations:

• An input variable position that accept 'top' | 'center' | 'center top' | ... as possible values. Depending on the chosen value, calculate top/bottom/left/right.
• More flexible for the user: allow the user to fill in the values themselves for top/bottom/left/right.
