I've been migrating my computer resources over from a 6 year old WXP
computer to a brand-new Debian Linux one. Most recently I tried to migrate
our old printer, a Brother MFC-420 CN printer / scanner / fax with USB
connection. Brother has CUPS and LPD drivers for it, and they have 2 sets
of instructions for installing the drivers (one pretty much automatic, one
more manual).

I've tried both sets of instructions, and it almost works. The printer is
detected by the computer when it is first connected; the install appears to
go correctly, and the printer appears correctly in the CUPS browser
interface. When I send print jobs, no errors appear, and the print jobs are
shown as "completed" in the CUPS browser interface. However, no printed
pages ever appear. Printing from the command line, applications, test
prints -- none of them result in printed output.

Has anyone else had problems like this? Any suggestions for how to resolve?

I realize that this is something of a long shot, but I have to say that the
responses I've gotten to questions and problems on this list have been
borderline-miraculous in fixing my problems, so I figured I'd give it a
shot! I've also asked the Linux support people at Brother for assistance.

Thanks in advance,
-PT

Additional information: looking in the error log, I see that I did in fact
get this error the last time I tried to print:

E [14/Jun/2010:22:35:43 -0700] Returning IPP
client-error-not-authorized for Print-Job
(ipp://localhost:631/printers/Mrs.Cat) from localhost

This looks like a configuration error (in cupsd.conf?), but for the life of
me I don't know how to fix it.

I finally found some time to look into this more deeply. Turns out it was
never a printer or driver problem at all. The problem was that my
cupsd.conf was set so restrictively that not even root could print! I
reconfigured so that root and I can print, and everything is now fixed.

Duh. Well, this is how Linux newbies learn, I suppose, and I'm having fun
in the process.
