Wireless printer Linux

gsimpson, Oct 2, 11:31pm
I can't print to wireless Brother MFC-990CW. It used to. I can still scan from the printer scanner.
Problem may be with Cups. Unable to connect. I get following message from Firefox
"Firefox can't establish a connection to the server at localhost:631."
Printer works with same machine in W7
Using Mint 11 64 bit

localhost is the PC, not the printers IP, is there a service or application supposed to be running on the linux box !

http://localhost:631/printers/ is the administration page for cups on the computer.

Entering this into Firefox on my desktop (on same network) opens cups admin just fine, shows printers MFC-990CW and PDF and prints ok.

The only recent changes are a new router. Laptop is wireless and desktop has cable to router.

sudo /etc/init.d/cups restart

Still no luck. Here is terminal copy

xx@xx ~ $ sudo /etc/init.d/cups restart
[sudo] password for gxxxxx:
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service cups restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop cups ; start cups. The restart(8) utility is also available.
cups stop/waiting
cups start/running, process 4126

So can you print from other applications! It kinda sounds like the problem is just firefox.

If I select the Cups PDF printer it works fine in any application including Firefox.
Brother will not print in any application or even a test page from 'Configure Printers'

Does the printer's Device URI point to a fixed IP address or does it start with dnssd:// !

And if it's a fixed IP, has the printer's IP changed!

gsimpson, Oct 3, 6:51am
It's pointing to dnssd://Brother%20MFC-990CW._p-
rinter._tcp.local/
It has a fixed IP 192.168.1.4

Under policies, I presume it's enabled and accepting jobs!

(also change the error policy to 'retry job' instead of the rather silly default 'stop printer')

gsimpson, Oct 3, 7:13am
Yes. That is how it is set up.

One thing that might work (often the easiest fix) is remove and reinstall the printer.

You could also check /var/log/cups/error_log for clues.
