I am unable to get a Brother MFC-J450DW to successfully print wirelessly from my Ubuntu 12.04 computer. On the other hand, my HP 6500 709n works well from this Ubuntu machine. The Brother prints wirelessly from the Windows XP machine. The Brother driver and CUPS was downloaded from the Brother site with the Ubuntu Software Center installing them (with a complaint about their structure).
I used the printer app to "Add Printer". I selected the network printer and did a find and it found two instances of it. I have an screen shot of that. So Ubuntu seems to "see" the printer. I used the defaults to finish the add process. But it fails to print.
Searching through the Ubuntu material and using a general Internet seach I found advice to put the IP address in instead of letting it default. It did that and it failed. That is not surprising given that the "find" process while adding the printer did find it on the network.
I also found this bug on one of the Ubuntu sites:
#987212 Wireless printer "Processing - Unable to locate printer." avahi (Ubuntu)
That seems to be specific to avahi which, I understand, has more to do with connecting to Apple gear than anything else. What that has to do with a Brother printer is not clear.
Here are the logs. What do you suggest I do next to get this printer working with Ubuntu?
