We have documented this in hplip.NEWS since 3.9.2.

Not good..

Thanks..

I have now documented this in the hplip.NEWS document, it isn't a Debian specific issue, this is imposed on us through CUPS.

You don't seem to be a member of lp nor lpadmin.

Given that hp-check does print the user groups a simple python mod should present an error message..

I'll leave this bug open until we can modify hp-check..
