Kill and restart HP communication processes
Version: 1.1.1The HP 33xx (specifically my 3330) software often loses the ability to connect to your printer/scanner, etc. It seems that killing off and restarting the background communication process sometimes solves this. Rebooting the printer can help too.
Operating System: Mac OS X
Bundled are a python script to do this for you and an application that you can double click if you don't like to type at a command line.
In case you want to run HP Communication reset from the terminal, don't forget about the chmod 755 hpcomm.py and chmod 755 hpkill.py Type pathtohpcomm.py/hpcomm.py.
