How to Print
Open print data file in an application, and specify barcode font, point, and language that you have set on the
printer driver, and then print it.
• The barcode size cannot be changed from the point set in [Specified Point]. If you specify a size other
than the specified one, the barcode is not printed.
• Some application such as .NET application may not be able to display or let you select the barcode
font registered by the printer driver. If that occurs, use the [Font Replacement] function of the printer
driver to replace a True Type font with the barcode font. See
Environment" on page 97.
