H Enter Heat Setting
This command changes the “on time” of elements of the print head. The default setting is 10 (except
in the case of printers with a menu, where the default setting can be changed through the keypad). An
increase or decrease in this value results in a change of heat applied by the print head to the media,
lightening or darkening the print contrast accordingly. This is helpful when using different media
types, each requiring a different amount of heat to properly image the media. The host device can
send this command value to correct the heat setting per the application.
Syntax: Hnn
Where: nn - Is a two-digit heat value (00-30)
Sample:
<STX>L<CR>
H15<CR>
141100001000100SAMPLE LABEL<CR>
E
The sample sets the printer for a heat value of 15 and prints one label.
 Note: Non-Display Models – the “Darkness Potentiometer,” while providing subtle changes, is intended to
be used to match print contrast levels following print head replacements.
J Justification
This command changes the printing justification.
 Note: Display-Equipped Models – This command is only valid for use with scalable fonts.
Syntax:
Ja
Where: a - Is a single-digit alpha character:
