Yep, me too. But I do remember that printers with more memory were capable of buffering the printout(s) on board rather than having to rely on spooling.

I can understand your argument about wanting it on the network. I'd prefer to use something like this as a central printer that would (hopefully) cut my printing costs.
As the vast majority of my printout are gray scale (I use about three times the number of black ink cartridges than I do color), this could be a good solution.

I can't find a Lexmark X203n in the US though. If HP wasn't relying on Postscript emulation I'd consider them.
