The Lexmark C534dn is designed especially for small to medium workgroups that don't want to lose time with complicated controls and configurations. Part of what makes it so easy to manage is its intuitive, newly designed operator panel. This includes a user-friendly numeric pad for easy PIN entry and network set-up. Print image files from your USB flash memory device using the convenient USB Direct Interface right on the operator panel. No need to open an application or a print driver. Simply insert and print!
