Comment 18 for bug 1245578

Didn't work for me with HP Officejet Pro 8610; I'm on Mint 17.1 Rebecca (based on 14.04).
I had hplip 3.15.4. I upgraded (hp-upgrade) to 3.15.6. No improvement on the jpeg front. So uninstalled it (hp-uninstall), installed hplip from standard repos. Still no improvement.
So I activated trusty-proposed and installed:
sudo apt-get install hplip/trusty-proposed
sudo apt-get install printer-driver-postscript-hp/trusty-proposed
sudo apt-get install hplip-gui/trusty-proposed

Now xsane wouldn't see the scanner at all.

I tried some hp- commands (hp-setup , hp-doctor , hp-scan , hp-uninstall) but they give errors (such as ImportError: /usr/lib/python2.7/dist-packages/hpmudext.so: undefined symbol: hpmud_make_par_uri).

I've now removed the packages from -proposed and put back 3.15.6 (with ongoing jpeg problem).
