Welcome to LQ chanelit and cmasonhung!
The best one-stop-shop for printing under Linux is
LinuxPrinting and if you haven't visited there yet, I'd recommend it. My understanding is that Lexmark printers use proprietary drivers (ie, the manufacturer has not released a Linux version) and thus configuring them under Linux can be more of a challenge than other manufacturers. I see that LP has a number of Lexmark drivers though, good luck with it
