Printing trimming guide lines in Lightroom

[RJS55]

When I intend to have a white border around finished prints, it would be great to have lines to guide my trimming.  I have a good roto-trimmer, but not the best at keeping things square. 

Is there a way to print say a box 1/4 inch around the print to guide the trimming?

Lightroom does not have a 'Print' module! So no luck there.

In Lightroom-Classic you might be able to have a work-around method:

Turn on 'Crop Marks' in Page Options, and Add a 'Stroke' border and change the color to 'white'. Trim to the Crop Marks.

        

Also- set print to 'Borderless' and Page Background to a visible color ('box') that you will trim away.
