I was very impressed by the customer service of 88Printers, the company that sold me this Lexmark E450DN. Before I bought the printer I asked them several questions about compatibilty with my old G4 operating system and other areas of concern. They responded within less than an hour, usually within minutes. All of their answers were correct and they gave me advice on finding the printer driver on the Lexmark website.Except for some tiny paint specs on the top (where someone must have painted around the printer), the printer was in "almost new" condition. Setup was easy and the machine worked perfectly with my MAC G4. The price was great and the printer arrived on the date as promised.I would definitely buy other merchandise from this company!
