If I print two pages of the score on one A4 page and set it to duplex, the reverse side comes out upside down relative to the front page.
I want to print 2 pages of the score on the front and 2 pages on the back. So if I turn the page over, the music is the same way round. I want to turn the pages over like it is a book. What setting do I need to use in the print settings?
Essentially this is which edge of the paper it gets ‘flipped’ on, to print the other side.
If you are printing a booklet, then you want Short edge, so that the sheet is flipped on the short edge, and the pages on the back are the same way around.
For single (portrait) pages on each side of the sheet, you want long-edge, because you flip the sheet along the long edge to read the other side.
