Summary: The T640n series is a workhorse work group printer that is network ready. It will just work (which is most of the time) once configured. I would own this unit. My complaint and only reason for a good rating instead of excellent, is that the unit is messy with toner at times and needs the cleaning...
Summary: Comments about Lexmark T640tn: we don't do massive printing, mainly smaller documents coming from a variety of different workstations. So this was the perfect printer for us. It operates well on the network, and it has the versatility and quality we need.
Summary: Comments about Lexmark T640n: Lexmark made an amazing printer in this T640n. It had no issues with our linux systems and best of all, it actually accomplishes what we needed to do. It prints on vinyl. We need all of our inventory labeled, and it's very humid where we keep our stock.
Summary: Nell'ufficio dove lavoro, alla fine dell'anno scorso sono state acquistate 8 lexmark T 640dn e, dato che mi occupo di gestione di rete essendone administrator, ho testato e installato personalmente le stampanti. Posso così affermare con sicurezza che è un prodotto molto valido ed efficiente.
Pros: Velocità di copia elevata
Cons: Costo del toner, come tutte le stampanti laser
