Qt/PyQt 4 initialization failed when installing hplip
If you found this error running hp-setup or diagnosed when running hp-check, just install python2-qt package. Run this on your terminal:
# pacman -S python2-qt
hp-check will give you all the diagnostic you’ll need to install your printer/scanner, in my case HP Officejet 4500, on your Arch installation.
