Questions about Telepen Alpha

Should I choose Telepen Alpha or Telepen Numeric?
Choose Alpha for references such as Asset-0042 that mix letters and numbers. Telepen Numeric uses different encoding for numeric data, so match the format expected by your receiving system. The check character is added automatically in both formats.
How do I check the code before printing?
Leave the white margins intact, keep the image in proportion and scan a sample at its final printed size with the device you intend to use.
