The problem comes when the icon that it defaults to for printing is a right load, but the only way that envelopes can be loaded is in the center of the tray. I have an HP Colorlaserjet 3600 and an HP Officejet Pro 8600 and both load this way.
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Now was can write a definition for Boolean functions. Definition A Boolean function is B k-> B m, which is the set of all functions that map k bit inputs to m bit outputs, where k >= 0 and m > 0. Recall what a function is, from your discrete math courses. A function consists of: a domain (the set being mapped from), a codomain (the set being mapped to),
