memory
The printer, like a computer, has a memory. When you print a file
from a computer, the contents of the file are transferred quickly
from the computer's memory to the printer's memory. The printer
then prints information from its own memory at a much slower rate.
This way of printing frees the computer to do other work while the
printer is still working. The printer memory is sometimes called the
buffer memory or input buffer.
