Additional printer memory on small boards called single in-line mem-
ory modules, or SIMMs, allows you to download more fonts, increase
the printer's buffers (where it stores data sent from the computer),
and duplex print at a higher resolution.
Your printer comes standard with 13 MB RAM and can be upgraded
through the installation of additional SIMMs to a maximum of 32 MB.
If you are replacing a 4 MB SIMM with an 8 or 16 MB SIMM, you
should first read the “Removing a SIMM” section of this chapter.
