Error: Invalid format for short nick name
I have a Brother MFC 9440CN, but I cannot print anything! An error message of "Invalid format for short nick name" shows no matter what I try to print from Safari, Preview, Excel, etc. I have deleted the printer and re-adding it, but it still does not work. I have tried connecting it directly via USB as opposed to via my ethernet network. I have run Software update. I have checked Brother web site but can see nothing of any use. I have the same problem on both my desktop (a Mac Pro) and a laptop (MacBook Pro). Any suggestions?
Mac Pro, Mac OS X (10.6)
