well, this is what i set up in LR
see img LR.jpg
This is the page setup dialog accessed by hitting the button in the lower left of LR
see img page setup.jpg
This is the dialog when you hit the properties button in the page setup dialog
see img props.jpg
and this is the result
The hand cut edge on the left is the edge of the roll paper that came out first. The glass case and the scissors laying on the print represent the left and right edges of the roll.
Not what i was expecting. From the screen in LR, I thought I was going to get two images side by side but LR printed them in sequence.
