Additional information: I check the above errors, and the rresults are below error list:

Versions of packages hplip depends on: ii adduser 3.116 ii coreutils 8.28-1 ii cups 2.2.5-1 ii hplip-data 3.17.9+repack0-1 ii libc6 2.24-17 ii libcups2 2.2.5-1 ii libdbus-1-3 1.11.20-1 ii libhpmud0 3.17.9+repack0-1+b1 ii libsane 1.0.25-4.1 ii libsane-hpaio 3.17.9+repack0-1+b1 ii libsnmp30 5.7.3+dfsg-1.7+b2 ii libusb-1.0-0 2:1.0.21-2 ii lsb-base 9.20170808 ii policykit-1 0.105-18 ii printer-driver-hpcups 3.17.9+repack0-1+b1 ii python3 3.6.3-1 ii python3-dbus 1.2.4-1+b3 ii python3-gi 3.24.1-3 ii python3-pexpect 4.2.1-1 ii python3-pil 4.2.1-1 ii python3-reportlab 3.4.0-3 ii wget 1.19.1-4 ii xz-utils 5.2.2-1.3 Versions of packages hplip recommends: ii avahi-daemon 0.7-3 pn printer-driver-postscript-hp <none> ii sane-utils 1.0.25-4.1 Versions of packages hplip suggests: pn hplip-doc <none> ii hplip-gui 3.17.9+repack0-1 pn python3-notify2 <none> ii system-config-printer 1.5.9-2 And after all this, I have been able to access the program by calling it from terminal using /usr/bin/hp-toolbox It has successfully set up the wireless network printer over the network. Could it be that the call from the main LXQt menu is incorrect, and not a bug in the hplip program?
