HP printer install fail

Question

I have a failed install of Hp printer at http://hplipopensource.com/hplip-web/install/manual/distros/ubuntu.html What I need help with is how do I Delete the printer software so I can reinstall. Also am I python 2 or 3? in 16.04 64 bit? I accidentally downloaded HPLIP double clicked the file and got an error message and clicked continue. Then I attempted a manual install i got

:~$ sudo hp-setup
[sudo] password for  

HP Linux Imaging and Printing System (ver. 3.16.3)
Printer/Fax Setup Utility ver. 9.0

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.

Also,

I had an error when using: Ubuntu 15.10 and 16.04 in python3 environment:

seemed to run when i used: Ubuntu 12.04 and above in python2 environment:

I have no idea whether I am python3 or python2.

I think once I know whether I am python3 or python2 I need to know how to completely uninstall my mistakes and then attempt a reinstall. I am a beginner so I may need to cut and paste the code for deleting my messed up install.

I am installing a HP officejet pro 8600. I can scan with simple scan and I print with my brother laserjet. Should i give up and just use simplescan since my 8600 does not even have ink. I was trying to get better scanning software.

Thank you for looking and any help.

Answer 1

you should run this

sudo apt-get install python3-pyqt4

Answer 2

It looks like it is complaining about stuff that should be installed. Actually, you should not have to "download" anything as all of this stuff is available through apt-get.

Run the following commands to install all needed software and drivers:

sudo apt-get update
sudo apt-get install hplip hplip-data hplip-doc hpijs-ppds hplip-gui hplip-dbg printer-driver-hpcups printer-driver-hpijs printer-driver-pxljr

Now, run one of the following commands:

/usr/bin/hp-setup --gui

or if that fails due to permission issues, run this instead:

sudo -i /usr/bin/hp-setup --gui

This version, 3.16.3, is the same version available from the hp website.

Please post any errors.
