I had exactly the same problem as described in the "bug description" with the 32 bit version of official Ubuntu release 12.04. The instructions of comment 11 did work for me, and I can now print a test page with the newly installed printer. However, I do not know how to set a "PPD" file per step 5 "Select the PPD file for the printer", because there is apparently no Properties tab under System - Printing - MFC7440N (not Printers as mentioned).
The next step will be to try to get the MFC7440N scanner to work in Ubuntu. (Printing and scanning both work fine in dual-booted Win 7, which is the best thing I can say about Windows.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873548 Title: Brother MFC 7440N printer is detected but will not print To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/873548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
