I have some backup keys that I want physical copies of, and I'd really like to be able to print it from tails. When I tried adding my HP deskjet 3520, it just gave me an error reading "failed to add printer" on the screen, so i thought I may need to install a driver. Can anyone here tell me how to do this or link a guide? Im running the latest tails (2.2.1) off a usb 3.0 with persistence enabled.
You need to find does tails support your printer. Open database say mostly works (hplip driver).
