I installed HPLIP on my raspberry pi to use CUPS as per here but some packages are simply not installing. I have tried:sudo apt-get -f install hplip, sudo apt-get install qt4-default qt4-designer qt4-doc qt4-dev-tools python-qt4 and the same for PYQT5, sudo apt-get install qt5-default and countless other things. Does anyone know what to do. My latest string (after doing all of the above and more for nearly 2 hours) is this: couldn't get the code snippet mode to work - don't know why.

MISSING DEPENDENCIES

Following dependencies are not installed. HPLIP will not work if all REQUIRED dependencies are not installed and some of the HPLIP features will not work if OPTIONAL dependencies are not installed. Package-Name Component Required/Optional
pyqt5-dbus gui_qt5 OPTIONAL
pyqt5 gui_qt5 REQUIRED
Do you want to install these missing dependencies (y=yes*, n=no, q=quit) ? y
