My house has two computers both networked together. The one upstairs runs vista, and the one in the basement runs XP. Recently the printer we had hooked up to the XP computer broke, and I am trying to network the printer upstairs (Lexmark Z611) to the one downstairs. I am having some trouble though, because while both computers recognize the Lexmark, only the one upstairs will print to it. The computer in the basement says that it has an error sending information to it. Does anyone know how I can fix this, so we don't have to run up and down the stairs just to print one document?
