NOTE Single inline memory modules (SIMMs) used in previous HPLaserJet printers are not
compatible with the printer.
The printer also has one EIO slot for expanding the printer networking capabilities. The EIO slot can
be used to upgrade the printer with an additional network connection, such as a wireless print server,
network card, or a connectivity card for a serial or AppleTalk connection.
NOTE The HP LaserJet M4345 Series MFP comes with a network device already installed.
The EIO slot may be used to provide networking capabilities in addition to those already built
into the printer.
To find out how much memory is installed in the printer, or to find out what is installed in the EIO
