It turns out it's easier than I was expecting. No voodoo! I got my
CueCat (usb version) today, plugged it in (on Linux, haven't tried
Windows yet) and scanned a barcode I generated. I tried it at the
console. It type out the correct part number and sent a carriage
return!
I'm using a script to generate the barcodes (3 of 9 or Code39):
http://www.sid6581.net/cs/php-scripts/barcode/
Just foreach through an array of part #'s
foreach($array AS $val)
echo "<img src=\"barcode.php?barcode=$val\">\n"; //see barcode.php
for other GET options
There are plenty of other barcode classes and phpclasses.org, but this
does what I want. Barcoding doesn't seem quite the mystery I thought
it would be.
Thanks,
Mike
