I was extremely lucky to spend 3 days as the guest of Dr Agnes and Dr
Jackson He at their home in Long Island about 10 weeks ago:

Jackson is best described as the "Barcode King".

It doesn't surprise me that the optical scanning on the iphone is
performing differently than the ccd or laser scanner on the conveyor are.
The laser/ccd is only going to scan in the 600-650 nm wavelength, which is
both good and bad. The overall width of the barcode shouldn't matter to
the scanner within the range that you will be dealing with. It's not
unusual for 1D barcodes to be the full width of an AIAG label.
I just googled "free 2 of 5 font" and found a bunch of entries. I'm not
using 2 of 5 so I can't speak to how good any of them are.

I could see how 'conveyor belt' could be easily lost in translation.

Yes, with iPhone and our USB scanners we are able to scan that “wider”
bars, but i am not sure the highspeed scanners of the carrier can.
The packages are scanned by high speed scanners while they are carried
and sorted on a“tractor tapes”. Btw, us tractor tape the correct
expression?
If the thermal transfer labels are accepted by the carrier then i will
add an option for the user to switch between laser and thermal printing.
The app will use different settings for laser and thermal printing.
So in case the TT printer is broken, they can switch over the laser
printer.

Out of curiosity, does printed barcodes from the laserwriter still work
with these settings?

I have to add something.
As I wrote, we were able to successfully scan the labels. This is true
as long as we print the labels with a laser printer.
If we print the labels with a thermo printer (203 dpi) then the code
cannot be scanned with the values i posted before.
We had set the line thickness of the rectangles to 0 and had to
increase the width of the black bars and decrease the width of the clear
ones.
So the code below shows the settings which allow us to scan the labels
with a Toshiba B-EV4D and a Zebra LP 2844.
put “3" into tNarrow
put “6" into tWide
set the width of grc "narrowC" to (tNarrow - 2)
set the width of grc "narrowB" to (tNarrow -3)
set the width of grc "wideC" to tWide
set the width of grc "wideB" to tWide
