But I can find anywhere in my print properties
of my programs to put it at two sides.
Try printing from a different program, e.g. a word processor.
The program can be the thing that tells the printer to do double-sided
printing, some programs might not bother with giving you the choice.
Firefox gives me no option to print double-sided, and only prints
single-sided. Whereas LibreOffice does, using the exact same printer.
Gvim printed something without asking me anything about the printer
(not even which printer), and printed it double-sided.
For instance, in LibreOffice there's a separate "Printer Settings" item
in the menu (separate from the print dialogue which will let you choose
which printer and some options). In the window it pops up, the
properties button for your printer has a duplex option.
And if you go straight to the Print item, the "properties" button for
your printer also brings up a window which has a duplex option.
I'm not sure about why there's two printing things which have a variety
of options that duplicate some features, but not others.
