Castelle Named Premier Partner in the HP Solution Business Partner (SBP) Program.

MORGAN HILL, Calif. -- Castelle[R] (Nasdaq:CSTL), a leader in 'all-in-one' network fax solutions for the business and enterprise markets, today announced that it was named a LanFAX Premier Partner in the HP Solution Business Partner (SBP) Program. The status was granted to Castelle based on the Company's valued integration work to build high quality fax solutions with HP's market-leading imaging and printing devices.

"We are very pleased to be selected by HP as a Premier Partner in the SBP Program," said Scott McDonald, President and CEO of Castelle. "Castelle has been an HP partner for over ten years and was the first to jointly develop an interface to the HP Scan Jet 5 network scanner. We continue to bundle the interface with our FaxPress[TM], FaxPress Premier[TM] and FaxPress Enterprise[TM] fax servers, and support a broad range of products from the Digital Sender network scanner through the color network multi-function printer (MFP) offerings. We look forward to working together in order to develop and market the solutions our customers need."

Castelle fax servers provide an ideal scan in, fax out solution for a variety of HP devices. Integrating FaxPress, FaxPress Premier or FaxPress Enterprise with these devices provides users immediate access to an intuitive, user-friendly fax interface. Paper documents are easily converted to electronic fax files with the touch of a button. Once a document is scanned, the digital sender or MFP is immediately free for further use, since all fax retries occur at the FaxPress.
