error: HPLIP is not installed properly or is installed without graphical support. Please reinstall HPLIP
warning: Qt/PyQt 4 initialization failed.
error: hp-setup requires GUI support (try running with --qt3). Also, try using interactive (-i) mode.
我该如何修复这个错误？
答案1
Hp 打印机需要qt4安装，因此安装时请使用：
sudo apt install python-qt4
然后再次运行hp-setup。
答案2
在 Ubuntu 17.04，HPLip 3.16.11 中，我需要：
sudo apt-get install python-qt4 python3-pip
pip3 install pyqt5
此后，HP-Setup 会以图形模式运行
