The k80 is no longer made so the 5110 is about the only way to go. We have deployed these to our remote, home office users. We have had some issues printing from Citrix (slow printing over dialup sessions, kinda expected) and with the printer wanting to recreate itself multiple times. This last is a consequence of our using XP and the fact that we put our users into the Users local group only. I would go for the 5110, but expect some issues.
