Setting Bar or Gap Index Type
All currently manufactured Cognitive printers support black bar and
gap indexing, and are shipped from the factory set for gap indexing. The
VARIABLE FEED_TYPE command controls the index method. Use one
of the following label formats to change the index type.
For black bar indexing:
! 0 0 0 0
VARIABLE FEED_TYPE BAR
VARIABLE WRITE
END
For gap indexing:
! 0 0 0 0
VARIABLE FEED_TYPE GAP
VARIABLE WRITE
END
Optimizing Index Detection
NOTE: This information is not applicable to Code Courier.
When using gap indexing in thermal transfer mode, the index detector
must "see" through the ribbon and detect the difference in opacity
between the label and the label backing. Variations in print media may
necessitate index detector adjustment in some cases. The VARIABLE
INDEX SETTING command controls the index detector sensitivity.
Direct Thermal Printing
The following label format will set the index detector for optimum
sensitivity when using direct thermal printing (that is, with no ribbon
installed):
! 0 0 0 0
VARIABLE INDEX SETTING 1
VARIABLE WRITE
END
