Bar codes can be printed on IPDS printers and viewed on graphics displays. They are not supported on page printers.

GDDM does not check the suitability of the bar-code font ID, module width, element height, height multiplier, or wide-to-narrow ratio for the target IPDS printer. Unsuitable values cause an error message to be issued and can cause the printer to stop.

When a bar code is viewed on a display, GDDM shows a generalized and stylized picture of the bar code, rather than an accurate representation. The following defaults are used if requested by the application:


   Module width                   014-inch
   Element height                 UPCA, UPCE,    1-inch
                                  EAN13
                                  3-of-9,        -inch
                                  2-of-5, MSI
                                  others         7/8-inch
   Wide-to-narrow ratio           2.5 : 1
