HH asked for a zero bleed margin

that software, good though it may be, does not enable a printer to print to the edge of the paper - either a printer does this, or it does not

you can clearly see in the video that the individual sheets that are printed off still have to be trimmed

I agree that, if trimming is acceptable, it will solve the page layout

BTW no way would I recommend you trim with scissors, that is very difficult to get right even with a steady hand and lots of practice, especially if you do not have the long bladed kind as shown - use a 'proper' trimmer
