I am trying to install this printer in ubuntu 12.04 LTS but I encounter the problem of driver downlaoding. I went to Brother's website and tried to install both LPR and cupswrapper driver but when I first install LPR driver it gives me a message of "The package is of Bad quality. The installation of a package which violates the quality standards isn't allowed. This could cause serious problems on your computer. Please contact the person or organisation who provided this package file and include the details beneath." Is there any easy way to install this printer?

Thanks a dozen.
