Lex Ross, I have checked and I see nothing in the error_log that any filter activates duplex. It seems that the wrong duplex setting happens in the SpliX driver executable.
If you print one copy af a job with more than one page, does this come out single-sided?
Can you provide your error_log of a failing job (3 copies of a one-page document)? Please follow the instructions in the "CUPS error_log" section in https://wiki.ubuntu.com/DebuggingPrintingProblems.
