4.3.1 Operating Memory
The printer operates using the currently selected values contained in
operating memory. When the printer is powered on, it loads the values
stored in NVRAM into operating memory. When you select new values
(through escape sequences or from the control panel), they are placed in
operating memory and become part of the printer settings that are currently
in use. Figure 4–3 shows the operational flow between the different types
of memory.
