Printer icon

[quinn]

I have a printer with exclamation point icon in the upper right corner 
(near the date box) of the top toolbar. It is there because it claims 
that I have a print job waiting that cannot print (I don't have the 
printer connected right now.), but it will not go away. If I open it up 
and choose to pause the print job and then cancel it, it will go away 
for a while, but then come back. I tried using a terminal, and lprming 
it as root, but that does not work, because it goes away for a while and 
then comes back. This is something that I tried printing months ago, and 
I did not have this problem until moving to Ubuntu a week ago.

How can I get the printer icon to go away and stay away unless/until 
there is a real problem?
