The HPLIP GUI subpackage provides graphic tools for the management of supported HP printers. These tools are not capable to run without graphical user interface, or they have unremoveable dependency on GUI modules.

- hp-makecopies - tool for making copies for HP AiO and MFP devices,
- hp-printsettings - printer settings tool,
- and hp-wificonfig - Wifi/Wireless/802.11 configuration tool for connecting HP printer to Wifi
This subpackage also provides GUI parts for tools shipped by the HPLIP base package:
- hp-align - cartridge alignment tool for HP inkjet printers,

- and hp-unload - tool for accessing inserted photo cards on supported HP printers (alternative for devices without USB mass storage support or for access to photo cards over a network).
The tools that do not need GUI for its functionality must be run with the '-i' option when the hplip-gui package is not installed.
The Launch button does not work because this subpackage is set of tools and it is not set which tool to launch from Gnome Software.
