EPSON Code39
❏ Four Code39 fonts are available, allowing you to enable and disable the automatic insertion of
check digits and OCR-B.
❏ The height of the bar code is automatically adjusted to 15% or more of its total length, in
conformance to the Code39 standard. For this reason, it is important to keep at least one space
between the bar code and the surrounding text to prevent overlapping.
❏ Spaces in Code39 bar codes should be input as “_” underbars.
❏ When printing two or more bar codes on one line, separate the bar codes with a tab, or select a font
other than a BarCode Font and input the space. If a space is input while a Code39 font is selected,
the bar code will not be correct.
