I am having some problems. This is what I need to be able to do.
Print a double sided score. Right now it is printing some blank pages. I want to be able to see the next page of the score when I flip the print. The pages should be in order from beginning to end.
Dorico won’t insert blank pages that aren’t included in your layout, so it sounds like there may be a problem with the printer. It should be as simple as activating duplex printing in the right-hand side in Print mode.
You could alternatively try exporting a PDF using the graphics export feature (again, using the options on the right-hand side in Print mode), then printing that PDF using an external application – if you’re on Mac, Preview is a good choice. Do you get the same unexpected blank pages when printing from Preview?
