Hi Srinivas, It seems that release 18.04.1 of both Ubuntu and Lubuntu fixes this problem, albeit with a bit of persistence, package installs, script running, and rebooting.
The printer/scanner involved is an HP LaserJet M1132 MFP Printer/Scanner, connected via USB cable. Note: I used these command lines to install the packages (yes, it is the long way round - but I wanted to spot anomalies). sudo apt install python3-pyqt4 sudo apt install python3-pyqt5 *lubuntu 18.04.1* I experimented with this first, using an old Dell Dimension E520 Tower PC. I went through with this process twice - yes, that was *two* installs of the O.S. I installed the O.S., a few other apps and then connected my printer. 1. Ran hp-setup. It requested that modules PyQt4 and PyQt5 be installed. 2. I installed python3-pyqt4, python-pyqt5 using the sudo apt install command. Rebooted 3. Ran sudo hp-setup . It ran to completion 4.Ran "Simple Scan" from the GUI. Failed to find scanner 5. Rebooted again. Ran "Simple Scan". It worked!! > *ubuntu 18.04.1* I also went through this process twice, on a lenovo ThinkPad T420. Simply connecting the printer when logged in is enough to get printing working - but *not* scanning. 1. I installed python3-pyqt4, python-pyqt5. Rebooted 2. Ran sudo hp-setup OK 3. Ran "Simple Scan" from the GUI. It worked! Now it is important to note that the information above came from my logbooks so there is a chance I've overlooked something. Thank you for your help.
