1.Paired digits represent the best-case compression. Adjacent digit pairs can be encoded into eight bits.

2.The implied compressibility requires the data be composed of either all lowercase or all uppercase characters with digits and spaces allowed.

3.Any ASCII character (0–127) can be encoded one-to-one, extended ASCII (128-255) requires an additional two-byte overhead.

Automatic Data Matrix Bar Code Generation

The printer automatically tests and changes the Data Matrix bar code geometry to optimize the

symbol size per the specified column and row (p4 - the c prefix and p5 - the r prefix) parameters. If no row or column parameters are specified, the printer will create a minimum size symbol based on the calculated compressed size of the data. The number of columns and rows in the symbol will be automatically determined with a preference towards the smallest square symbol that will accommodate the compressed size.

The user may wish to force the number of rows and/or columns to a larger value to achieve uniform symbol sizes.
