a keyboard wedge or serial port.
To add to what Emile mentions, most barcode readers present a
keyboard-wedge interface, so that scanning a barcode merely appears as if
you typed it at the keyboard (USB readers show up as a HID profile). Often
they'll have configuration barcodes that you can scan
digits as an index into byte-strings of MX-80 codes.
I've recently downloaded the 4-state spec from USPS... That thing is
obscene... At least Postnet could be decoded visually with a simple
chart. 4-state distributes bits all over!
well the code in reportlab/graphics/barcodes that deals

That looks cleaner than mine. I had to do this -

# Don't want to push the font out to everyone in the office...

Damjan,
Code39 here refers to part of the Barcode Extensions available to
Reportlabs. It can be imported as such
from reportlab.extensions.barcode import code39

This may not help you directly, but I've made use of it in the past: a
very nice and totally free 3 of 9 TrueType font.

Benji,
I have used those very same fonts before and they work great, but I'm
trying to get away with using straight Python to accomplish this,
especially since the program will most likely be used on both Linux and
Windows.

One of the users on the Reportlabs mailing list was kinda enough to
offer me the solution.. A simple call to the drawOn function, e.g.:
bc = code39.Standard39(123,xdim = .015*inch)
x = 6*inch
y = -5*inch
bc.drawOn(canvas,x,y)

Hi All,
I need someone to explain to me how to output a Code39 barcode to a
Reportlab PDF. As far as I can tell, there is no means to do this with
the Canvas object, and the demo that is included with the libraries is
using the platypus Frame to place the barcode on the form. I do not
wish to use
