Hplip device communication error 5012

[Rob Singelais <rsingelais2@gmail.com>]

I installed the hplip package and when I open the hp-toolbox as a user I 
get this error under status that says "Device communication error 5012". 
If I start hp-toolbox as root I don't get this error. Is this a 
permission error, how would I correct this?

Thanks
