All your ideas are great, but we are just so far behind all you guys, we have a networked ICT suite leased from RM (before my time) with a storebox and 2 HP laserjets (1020 b&w and a 2550 - colour). No other network around the school apart from a wireless connection routed through the school office network into 3 classes (out of 12).
We have a real mish mash of printers in classrooms mainly Canons and Epsons with a smattering of HP deskjets mixed in. To refill each deskjet printer I would need to order 18 different types of cartridges including 9 of the HP variety.
What would your suggestion be, seeing as you now have a basic understanding of my situation? Is it possible to hook the 3 computers in the wireless connected classrooms into the schoolshare network in the Suite and make them print to the laserjets?
