bar-code reader & printer

[John Bowe]

We are investigating using bar codes for tracking documents. We'd like to
print bar codes, then attach them to documents, read the bar codes with
the system (sun4) recognizing the numbers.  I've heard rumors of scanners
run off ibm PCs.

Is anyone familiar with any products/packages to:
	1) read the bar codes under a sun's control
	2) print bar codes (preferably on a PostScript printer)
