这台打印机很旧，但它打印的测试页看起来仍然非常好，黑色质量非常好。所以我想进一步使用它。
我正在运行 Debian 8.6，我尝试了发行版中的“hplip”，我可以添加带有杯子的打印机，但随后我得到：

好吧……它就是行不通。所以我清除了“hplip”解决方案并直接从 hp 尝试了“hplib.run”。我知道这会将 apt 不知道的文件安装到系统中......但我对此很满意。我希望我的硬件能够工作。
运行文件显示：
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 REQUIRED
libcrypto network REQUIRED
libnetsnmp-devel network REQUIRED
sane-devel scan REQUIRED
pyqt4-dbus gui_qt4 REQUIRED
cups-devel base REQUIRED
pyqt5 gui_qt5 REQUIRED
libtool base REQUIRED
cups-image base REQUIRED
xsane scan OPTIONAL
dbus fax REQUIRED
avahi-utils network OPTIONAL
当然，还有第一个包：
pyqt5-dbus
8.6 中甚至不存在，该驱动程序显然是为 8.5 编写的。
有办法解决这个问题吗？
“hplip”是否真的需要安装这个确切的软件包，还是使用不同的软件包实现的功能，以及它们是如何调用的？
