Wrong code interpretation:
When I have build a barcode sheet some years ago, I have noticed a wrong interpretation when using very short printed barcode, nearly from 12 to 13.5mm length. (allowing up to 11 possible functions horizontally on A4 format).
I cannot remember the function (it was with HP-IL functions of Ext. I/O or Dev. modules) as I dit not keep the original uncorrected document, but when using the same density as other codes it was interpreted as another function, so I had to enlarge by 8% the barcode of that function to get back the right interpretation.
I have tried on 2 different Wand 1F with the same results.
Just for the fun I would be interested in similar experiences of others with the Wand.
