Always print bar codes as large as possible, not as small as possible.
Larger bar codes are easier to read.
If your bar code reader is configured to test check characters, then you must print bar codes with check characters. This applies to; Code 39, Interleaved 2-of-5 (ITF).
Alternatively, you must configure your bar code reader to not test check characters.
It is usually to print only UPPERCASE characters, not lowercase characters. Lowercase will produce a bar code, two times wider than UPPERCASE.
If you are using the full version of JIT-SBP and when you read the bar code, you see strange characters, then you must configure your reader to accept Extended Code 39 characters.
When you read the bar code, if you see 0 at the start, this is correct. The length of all Interleaved 2-of-5 (ITF) bar codes must be even; 2, 4, 6, 8, etc. So 0 is added, if the length of the data is not even; to produce an even length.
If you are using a low resolution printer (200 dpi thermal type by; Intermec, Eltron, Zebra, C Itoh, TEC, Datamax, etc.) please request information about special bar code fonts for this type of printer.
