I have a schematic with two sheets; 1 schematic sheet, one BOM.
I selected Print and Printer Settings, and turned on Duplex.
I printed two separate sheets, rather than putting the BOM on the backside of the schematic.
Printing not honoring duplex setting
Re: Printing not honoring duplex setting
You can open print preview, setup sheets, click on print all button, choose a virtual PDf pinter and save PDF file with two sheets. Now open the file in Acrobat Reader or other PDF viewer and print from it. Acrobat Reader has more print settings than DipTrace.
