HP Envy – Duplex

 

I decided to try and figure out how I can actually print double sided on my HP Envy 5530 printer.   As I am using Debian 9 with LXDE desktop.   It turns out this is easy.

Within the print dialogue box,  click on page set up tab and select long edge.  This will then print documents double sided without the hassle of you having to remove paper, put the paper back in and print the second side.    This saves paper too.
