Odd question about CUPS

[Tom Allison <tom@tacocat.net>]

I have a cups server that has been working perfectly for several years. 
 Recently my Debian and Macbooks (Firefox only) where all upgraded and 
now the printer does not work for the macbooks.

Here's the CUPS error entry:
cupsdAuthorize: No authentication data provided


here's the fun part.
It works perfectly from MS Word on Mac and OpenOffice on Mac.
It doesn't work for FireFox, Thunderbird or Preview (Apple PDF).

Because of the OpenOffice and Word I was thinking that this is not a 
problem with the printer configuration and that it might be a problem 
with recent upgrades to FireFox.  Except my wife, who did not upgrade 
FireFox has the same problem.

Add to that the fact that the Preview can't print either (not upgraded).

I'm currenlty, because of the error, of the opinion that my Debian 
printer server has taken a turn for the worse.

I have no authentication that I recall adding.
There is something that might be new - CUPS-Authenticate-Jobs that I'm 
not familiar with.

But if this is server related -- how does OpenOffice and MS Word get 
around this?  I'm really in a jamb here because I *need* my printer for 
college.
