lexmark are shite... they are really expensive inkwise, the running costs are massive compared to other printers. They do not have high number of pages respective to each cartridge.
Not to mention the quality produced by lexmark is questionable
I would suggest buying a wireless print hub simply because you are then not restricted to your choice in printer now or in the future... I have a Netgear Wireless Printserver with 4-Port Switch which has a Canon IP 5000 connected to it and a Epson photo scanner
