I understand now. You would at least like the option to print on both sides even if it is just manually. I am surprised your printer doesn't have that feature. I have discovered in Microsoft Word, I have that option if I use the Deskjet 990c driver. The only option when I use your printer is to print every other page. If you would like this feature, you can assign an alternate print driver to your printer and switch to your original driver when you need it.

I hope this will work as a solution for you.
Keep me posted.
