I've added bar coded fields to our packing slips and we noticed that some of our part numbers that are less than 4 characters do not scan at all.  Walter did some testing and determined the fields have to be at least 4 characters for the field to scan, no matter what format (code 39, code 128, ascii, etc.).  Why is that?  We can get the fields to scan if we add a couple of spaces in a two character part # field, or 3 spaces in single character part field.  But will that mess up Evo some how, some way, at some point by putting spaces in part # fields?
 
How do we get around this issue?
 
Also the spaces add a carriage return, which is good and also bad in some cases.  
 
Thanks,

After doing some research, there is a minimum and maximum on bar codes for Code 39 (and 128, ASCII, etc.--we use Code 39).  Anyway, it appears 4 is the minimum, so anything less than 4 characters will not scan.  I did discover, however, it may be possible to "reprogram" our hand held scanners to accecpt less characters by changing a global parameter in the scanner.  Just  have to figure out how to do it with our scanners.
 
But I assume it's not a good idea to allow Walter to just add spaces into the part #s in Evo?  Like changing a Part code W to W(space)(space)(space).

I was able to successfully reprogram the scanners to accept 1 character barcodes.  We are all set.  A simple solution.
