User`s guide

In its permanent memory (ROM), the printer stores all the factory
default choices and resident fonts.
In its long-term memory (EEPROM), the printer stores choices not
likely to be changed on a daily basis, such as emulation mode. These
things stay in memory even when you reset or turn off the printer.
In its short-term memory (RAM), the printer stores the current page
data, downloaded fonts, and any other data used to print the current
page. Turning off the printer erases everything in short-term
memory.
