In the world of Windows, a printer is not actually the machine that creates paper versions of your electronic data. That's a print device. A printer is the software interface between the print device and the operating system. But that's different than a print driver, which is the software that allows the operating system to communicate with the print device. A printer pool is a series of print devices associated with a printer, and a print server is the network server on which printers are defined.
