Just trying to save as much space on a form with bar codes. We are using code 128 ( we could use others). Is there a magic formula to determine how much space a bar code will need to be scanned with a high degree of readability? We are using hhp 7200. laser printer 600 dpi. Is it trial and error to determine the smallest width and height etc.. We are using crystal reports to generate bar coded warehouse pick tickets.. Is there a min font size.. I have been just been going on trial and error with more errors than success.. Is there a magic formula to reduce space and achieve high scan success rates???
