hplip

[tuesdaybarrett]

I have a hp desktop all in one printer,copier and scanner. I don't use it that often but yesterday I wanted to scan something and I got message of communication device error 5012. So i removed hplip 3.20.5 and downloaded newest release of 3.20.6 I followed the instructions some error messages were on the terminal but i continued on. The program recognized my printer but still got the 5012 error. How can this be fixed. Can anyone provide step by step instructions to fix this problem? Any help would be appreciated.

The above exception was the direct cause of the following exception:

should i enable QT5 via this?How to install HPLIP with qt5


Notes:
HPLIP supports Qt5 from 3.16.5 and above
To enable qt5 support:

1. You need to install the following dependencies
   
   • PyQt5
   • python-qt5-dbus
   
   
2. Go to source of hplip. By default it is in ~/Downloads.
3. Run the following commands
   
   • ./configure --prefix=/usr --enable-qt5 --disable-qt4
   • make
   • "make install" as root user

Always better to use the ubuntu package manager to install software rather than an internet site like sourceforge. Which version of ubuntu are you running? I have 20.04 and using the synaptic package manager I see that hplip 3.20.3 is available. Using synaptic would be the preferred way to install hplip.

I'm using ubuntu 20.04/ Installed synaptic package manager & then installed hplip but still get communication device error 5012

Try removing the printer, uninstall hplip, reinstall hplip.
