Here's an alternative suggestion. You can use cups to create an
"instance" of your printer that does double-sided printing by default.
All you need to do then is to tell your application to use that instance
of the printer.
Let's say your printer is called "laser". You can get a list of the
available print options for the printer using the "lpoptions" command:
$ lpoptions -l -p laser

This is a list of the options the printer supports. The one you're
interested in is "TR-Duplex" (it may be called something else on your
printer).
What you can do now is create a new printer instance called
"laser/duplex" (just for your use, not a system-wide setting) by
running:
$ lpoptions -p laser/duplex -o TR-Duplex=True
You now effectively have two printers: "laser", which has duplex
printing turned off, and "laser/duplex", which has duplex printing
enabled. Just use the printer instance "laser/duplex" instead of "laser"
when you want double sided printing.
If the lpoptions command is run as root, it can set up printer instances
on a system-wide basis that will work for all users. See "man
lpoptions".
