Is there a reason you want colour laser over colour inkjet?
You wont get photo quality pics out of a laserjet without paying a lotta money for the printer so that is worth bearing in mind... If you want a network laser colour printer then id recommend something like:
HP Color LaserJet CP2025n
takes 300 sheets at once
has a network port to put it on your LAN
600x600 dpi
20page per min speed
Currently costs £365 on PC World Business site.. Also bare in mind colour laserjets have toners for at least black/magenta/yellow/cyan. Each toner will cost around £100 to replace which is where most vendors make all their money via printer running costs.
PS If you need wifi plug its network cable into a wireless router/access point...
