I currently have a Brothers HL-2140 printer wired to my Mac. I installed Bonjour onto my PC so that I can print wireless. I believe that the installation went well because I can see the printer when trying to print a document. However, when I print I see that the printer receives the data but there is no ink on the paper. It's just a blank sheet or sometimes there is a little bit of ink. It's a brand new printer so ink is not an issue. When I print from the Mac there is absolutely no difficulty. Thanks again. Any suggestions?
