Epson HX-20 - Manual (Page 63)

A bar code reader can “read” bar codes-those patterns of black
and white stripes you find on groceries, magazines, and so many
other products today.
As of this printing, Epson has provided only the hardware inter-
face for a bar code reader. But when you read this, a bar code reader
might be available. Contact your Epson dealer. If you purchase a
bar code reader, be sure to see what software is available for use with
it.
