	The HP ScanJet 4400C has a flatbed design. It has a optical resolution

	and a B&W document in about 35 seconds. It supports both parallel
	and usb connection. This scanner is PC/Mac compatible. It also
	includes 5 configurable buttons.
	Release Date:	Q4 2001

	ScanJet 4400C, 4470C            These scanners uses a RealTek
	RTS8891 chip to drive the scanner. Requests for information
	on this chip to RealTek have gone unanswered. There is some
	very preliminary software for these based on reverse
	engineering the Windows driver. More information on this
	can be can be found at SourceForge here.

	michael.cohen at netspeed.com.au has got it working in grey scale etc

	I have spoken to HP about this. The scanner uses a parallel
	port but has a USB to parallel converter in it.

	There is a demo SANE backend for the HP ScanJet 4400C and
	4470C at http://hp44x0backend.sourceforge.net that can do
	greyscale scanning at 300 / 600 DPI.
