Barcode Forums by Morovia

I'm having a problem when I try to scan a Code 128 font (registered). What I want to do is print a barcode using the Mrv Code128S font non-homan readable. I'm using the VB function I got from your web site called Code128B. If i use the font Mrv Code128bSA it prints and scans fine (though i get the check sum digit which i don't want to see, can't figure out how to turn it off). If I use font Mrv Code128S,M,X etc it prints but will not scan. I even used the encoded value from FontPal with the same results. WHat am I doing wrong?

thanks.

Can you post the the data and the barcode string (the result of the function)? If you are not comfortable with posting the data here, send an email to support@morovia.com with the data.

I don't mind posting. Here is a samople of the data I'm trying to print

22004S0000023443

Here's what FontPal returns as

Code128A È22004S0000023443`ËÍ

Code128B É22004S0000023443aËÍ

Code128C Ê"4$ÌÌ"BK@ËÍ

Code128Auto Ê6ÌÅ4SÄÌÌ"BK8ËÍ



Here is the same data using the VB functions from your web site that i'm using

Code128A È22004S0000023443`ËÍ

Code128B É22004S0000023443aËÍ

Code128C Ê6ÌHÌÌ7L>&ËÍ

Code128Auto Ê6ÌÅ4SÄÌÌ"BK8ËÍ

By the way, do you know if i can take these fonts and copy them into a Windows Ce device? That's the whole point of my doing this since i have to print a barcode from a handheld scanner.

I tried the code128B barcode string with three fonts - code128SA, Code128S and Code128M. All barcode scaned just fine. I suggest that you increase the point size to 18 or 20 and print again.

We have not done testing on Windows CE but you should be able to use the fonts on a Window CE device. Let us know if you encounter any issue.

The extra checksum is required by the code128 standard. Without it the barcode won't scan. To get ride of the extra checksum you can use a non-human readable font. These typeface names without ending capital A are non-human readable version fonts. There are 5 non human readable code128 fonts.
