printer

A logical name that points to an interface file, which represents a physical device, that is, the actual printer.

class

The name given to an ordered list of one or more printers. A printer may be assigned to more than one class, but need not be a member of any class. Figure 2-2 shows printers divided into two classes: one for black and white printers and one for color printers.

destination

The place an lp request is sent to await printing. The destination may be a specific printer or a class of printers. An output request sent to a specific printer is printed only by that printer; a request sent to a class of printers is printed by the first available printer in its class. Default destinations are initially set up but can later be modified, as needed.
