I have a MacBook OS X 10.5 and a desktop computer with Wondows XP Home edition. A Brother HL 2040 laser printer is connected to the desktop computer and I want to configure the MacBook to print over the network. I've tried clicking on "Add Printer" from the Printer popup menu, but do not see my printer in the Windows tab. I've also tried what the website says to do at http://guides.macrumors.com/Printing_to_a_Shared_PC_Printer, but it won't let me go through all the steps. Please help?
