I am using VS 08 , crystal reports, Mysql for a small inventory system. In my case I am going to print the barcodes and also generate them. I have used various fonts and I cannot get the scanner to scan them. It scans whatever barcode I test, other than the ones that I generate. I tried printting on paper A4 and on the label A4 but not scanning. I made some mockup barcodes to test the length and characters it can read. I found out that when I enter normal, long barcodes they are not scanned. I was succesfull in scanning some 3-digit barcodes and 4-digit. I could not scan anything more. I am using Barcode39 with font size 16. I am testing the printouts on two completely different scanners. Both of them work the same in scanning my barcodes. Which that means they ony scan small character sequences. Anybody with some help. Thanks for your efforts.
