Values of all the adjustable bar code parameters ar e stored in NVRAM while power is off. You

can restore the bar code attributes to the factory setti ngs by performing an ISU on the printer.

General Rules for Assigning Parameters

 You can send the sequence to modify bar code parameters any time except when bar code

mode is active.

 If you assign a parameter value outside the permissible range, then that parameter value

reverts to the default value.

 Values for narrow bars must be less than values for wide bars. Values for narrow spaces

must be less than values for wide spaces. The ratio be tween wide and narrow elements

should be about 3:1.

As with other ANSI escape sequences that take multiple parameters, you can use the semicolon

as a place holder when you want to change a higher-num bered parameter while leaving lower-

numbered parameters alone. For example, to set the hor izontal print density to 60 dpi without

changing any other bar code attributes, you could send:

ESC [;;;;;;;;;0;;}

Semicolons that trail the last specified parameter ar e optional. For example, to turn off the

human-readable line without changing any other parameters, you could send:

ESC [;;0}

Or, you could send:

ESC [;;0;;;;;;;;;}

Note: The term “default” is misleading when applied to bar code param eters. This printer stores

bar code parameters in nonvolatile RAM while power is off; except for an ISU or an out-of-range

argument, you might never see the effects of the fac tory defaults. For this reason, your

application should probably initialize all 12 p arameters one time before any symbols are sent.

This is particularly true when other bar code applications ar e sharing the printer.
