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.
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.his means that if the object $x$ is in the set of inputs (called the domain) then a function $f$ will map the object $x$ to exactly one object $f(x)$ in the set of possible outputs (called the codomain).
