Printing bar codes

Not all printers support BCOCA. If your printer does not support BCOCA, you can still print bar codes by producing them with a program that does not give BCOCA output, or by using fonts.

Printers that support bar codes support different bar code symbologies and symbology parameters. Your printer can use default values for unsupported parameters; therefore, verify that the bar codes printed by your printer are suitable for your purposes. Bar codes generated on printers with different resolutions can differ in length because of the resolution correction needed to round the bar code widths to a specific pel size. Each printer can use a different algorithm for this calculation; therefore, you need to test on each type of printer to be used to print bar codes.

For information about the bar code support that your printer provides, see the documentation provided with the printer.
