Windows vista printing problems?

I am logged onto the college network via wireless wifi on my laptop. I have Windows Vista Home Premium. I want to print to the school's printers, and I am told that it is possible, but i can't figure it out. I would consider myself fairly knowledgeable with computers and i have installed the drivers for the printer I am trying to install, but it always says that it cannot find the .INF file it needs. I've tried almost every driver available and nothing... help!
