Lasting value

part of the purchasing decision. Both the versatility and
reliability designed into the HP LaserJet 4345mfp series
contribute to significant cost savings over time.

paper-handling capabilities enables you to produce
documents locally. With the productive MFP, you can

centralized printing.
Reliability saves money. By far the biggest contributor to
user productivity and low cost of ownership is the reliability
of HP equipment, support, and service. For over a decade,
Hewlett-Packard has consistently received the top grade in
PC Magazine’s Service and Reliability Survey and recently
received one of the first-ever A+ ratings. Instead of
experiencing frustration and expensive downtime, users
can get their work done!
Add the following optional components and build an MFP to meet the needs of your business.
