1 Product information
The HP LaserJet M4349x is designed to be shared by a workgroup. Use the MFP to copy and print
black-and-white documents or to digitally send black-and-white documents. The MFP is a standalone
copier that does not require connection to a computer. With the optional HP LaserJet Analog Fax
Accessory 300 User Guide (included with some models), the MFP can also send and receive faxes.
If you have not done so, see the HP LaserJet M4349x Getting Started Guide for setup instructions.

NOTE: An automatic duplex printing accessory is required
for two-sided copying.
NOTE: To use e-mail functionality, the device must be
connected to an IP-based server that has simple mail transfer
protocol (SMTP). This server can be on the local area network
or at an outside Internet service provider (ISP). HP
recommends that the device be located on the same local area
network (LAN) as the SMTP server. If you are using an ISP,
you must connect to the ISP by using a digital subscriber line
(DSL) connection. If you obtain e-mail services from an ISP,
ask the ISP to provide the correct SMTP address.
Dial-up connections are not supported. If you do not have an
SMTP server on your network, you can purchase third-party
software that allows you to create an SMTP server.
