Darkroom Booth 2.5 or Higher | Documentation
The strip alignment comes preset and should be close but printers vary and with paper changes may need slight adjustments. With the DNP DS40, DS620A and the RX-1 there is a centering adjustment that allows you to fine tune the centering on the cut line. The photo below shows a 2x6 print oriented how it comes out of the printer. In the printer properties dialog window there is a Fine Adjust section. you can enter negative or positive numbers to move the 4x6 image up and down or side to side.
The bleed may also be helpful this will give you the option to zoom in or out.
