Depends on your definition of support, but most EPSON scanners will
work under Linux.  That does not mean that all functionality listed
in the product specification is supported for all models.  For most

of functions are supported in software and is only available in the
Windows/Macintosh drivers included in the box (and downloadable via
an EPSON site near you).
