I was an HP Customer Engineer from 1995-2002.

During this time, I serviced contract and warranty calls within the Northern Indiana area. When I left HP, I took my Designjet service experience and started my own business servicing out of contract plotters. Designjetpartsfast.com was launched in 2009. With over 28 years Designjet experience, I can help you resolve issues you are experiencing with your Designjet Printer.
