My system:
$ uname -a Linux rat 4.9.43-39.lts #1 SMP Sun Aug 13 11:11:18 UTC 2017 x86_64 GNU/Linux $ lsb_release -a LSB Version: 1.4 Distributor ID: Solus Description: Solus Release: 3 Codename: shannon
My printer, which is a HP Deskjet Ink advantage 1515, is configured with a HP Deskjet 1510 Series hpijs, 3.17.7 driver. It worked great in the previous version, and now I only can print because simple-scan doesn't see the scanner. Trying to configure stuff from hp tools, I noticed that I could add the printer using hp-setup only when using sudo, like the connection was refused because I was not root before. So when I run "sudo simple-scan" it works normally, which is a insane workaround.
