Hi Srinivas,
*I see two devices when you do "scanimage -L".See if you have two devices even when you do "hp-setup".You can remove the below device using "hp-setup -r" and see if scan works. device `hpaio:ecthp:/usb/HP_LaserJet_Professional_M1132_MFP?serial=000000000QH67JHFPR1a "HPLaserJet Professional M1132 MFP" "HP LaserJet Professional M1132 MFP USB000000000QH67JHFPR1a HPLIP" "MFG:Hewlett-Packard' is a Hewlett-PackardHP_LaserJet_Professional_M1132_MFP all-in-one* As asked, removed the one with underscores in its name. Got an error message window:- "Failed to scan. Unable to connect to scanner". *Also you can try the below commands,$ cd /usr/lib$ sudo ln -s libhpmud.so.0 libhpmud.so* As asked, performed the above commands:- ian@newton:~$ cd /usr/lib ian@newton:/usr/lib$ ls -lhrt libhpmu* -rwxr-xr-x 1 root root 403K Jun 10 18:38 libhpmud.so.0.0.6 lrwxrwxrwx 1 root root 17 Jun 10 18:38 libhpmud.so.0 -> libhpmud.so.0.0.6 lrwxrwxrwx 1 root root 17 Jun 10 18:38 libhpmud.so -> libhpmud.so.0.0.6 -rwxr-xr-x 1 root root 997 Jun 10 18:38 libhpmud.la ian@newton:/usr/lib$ sudo ln -s libhpmud.so.0 libhpmud.so [sudo] password for ian: ln: failed to create symbolic link 'libhpmud.so': File exists ian@newton:/usr/lib$ Printing still works, though.

Intel i5-2520m 2.5GHz 64-bit CPU, 8GiB RAM, 298GiB hard drive, DVD writer, Ethernet and WiFi connections. Attached my LaserJet, Ubuntu ran some software to install the printer (probably trying to run the HP software) and /usr/lib/cups/filter/hpcups crashed with the assertion failure: free(): invalid pointer. Rebooted, installed package hplip-gui, ran sudo hp-setup – it needed to ask me (the user) some questions. That kept it happy and it ran successfully. I ended up with two similarly named HP Printers. Printed to the right one and it worked. Renamed the other one to avoid confusion whilst printing.
