Bar Code Commands
To print bar codes with the Native 4247 commands, use the SELECT and PRINT
commands. Both commands are required.
Command

Note: The PRINT command will permit multiple bar codes to be printed on a single line
using a single PRINT command. You also may issue multiple PRINT commands for a single
SELECT command, if the format and bar code topology do not change.
The following pages show the general command structure for all bar code types.
See "Valid Bar Code Data" on page 177 for specific bar code types, valid data field
