[newbie] whew-boy help again

[Don and Alexa Pongracz]

Well, I've gone a redone a bit. First my printer didn't work, and I thought perhaps it was the settings, although they seemed okay. Then it hung...my fault, and then I rebooted.  The printer still won't print, I now suspect it is out of ink, and the one red warning is this: dhcpd failed   and now my internet won't work. Question one: what remedy would work Question two: would the settings I had in place perhaps change as I had to shut the computer off when it hung?? Any help would be appreciated.   Alexa
