I had the same issue, working in version EE7.9.1.
Using the "Export to pdf" functionality should solve the problem.
Worth noting that even Export pdf wont solve the problem with the , literally amazing, decision to not allow anything more than 32 imported objects into a schematic. So, if , like us, you use a bitmap for a company logo on your schematic sheets, be aware.
The limit of 32 embedded objects will be removed in the EE7.9.2 release due later this year.
