Wow. That's amazing, as Lexmark for several years has had miserable support for Linux.
One of my printers is a Lexmark X1270 all-in-one. The printer works (with minimal features) with the z600 driver stuff (can't remember the exact name). I'm glad it prints at all. The scanner part has had a working driver through SANE for a year or so but the driver was very poor. There were always faint background streaks that do not appear in Windows with the same scanner. However, things have improved greatly in VL6 SOHO beta 4.4x. No streaks! The copier function in Windows requires that the computer be on and works through Windows-only software. There is no copier function for the scanner in Linux.
I doubt Linux-friendly Lexmark will filter down to decent drivers for cheap older models like the X1270. I hope Linux support will extend through the whole new line of printers.
