Barcode fonts in the active document are appearing as boxes or another font.

When a saved document, with a barcode symbology, is opened in any application the barcode on the Active document appears as boxes or another installed font. The missing barcode font has not been installed through the Windows Printer Driver, or the Windows Printer driver itself has not been installed. Therefore the application is substituting the missing barcode font for a font that is already installed.

Install the missing Windows Driver through the Add Printer Wizard or install the missing barcode font through the Windows Driver applet.
