Enabling double Sided printing
I have a MacBook with 10.14.4 MacOS Mojave and have recently bought a wireless HP Printer Deskjet 2600.
I'm trying to enable double sided printing however when I go to print my document, it won't even allow me to edit from single sided to double sided printing; I've gone into system preferences to edit it but there's no option anywhere. I'm not very tech savvy so this is really infuriating me.
Does anyone have any ideas? I would really appreciate it.
Thanks in advance.
