Hi, I have a duplex printer and I've set it up such that the default preset when I print from an application is for duplex printing. I want to be able to do batch printing, and it seems like creating a desktop printing and then dragging-and-dropping is the easiest solution (please tell me if I'm wrong). When I drag files onto the desktop printer, it prints single-sided. Is there a way to make the default duplex (or, more generally, to make the default a particular preset that I've set up)? Thanks.
