VARIABLE MEDIA_ADJUST
Function Adjusts print contrast on object leading edges for
optimum print quality. Adjustment of this
parameter is not normally required, but may
improve rotated bar code reliability in some
circumstances. Printers that support this command
employ an advanced "dot history" algorithm, which
tracks the activity of each printhead dot from one
dot row to the next. If a given dot was off prior to
being commanded on, the printer will apply a little
extra energy to the dot to force it to come up to full
temperature faster. This can significantly improve
the reliability of rotated bar codes. This setting is
independent of the VARIABLE DARKNESS setting,
and only affects the first dot row of each object (or
for rotated bar codes, the leading edge of each bar in
the code).
NOTE: This feature is only active when printing at 2 IPS
with 200 DPI print pitch.

Parameters
n
Media adjust value. The allowable range is -
3000 to +3000. Fast media – media that
prints well with low VARIABLE DARKNESS
values – will generally print better with high
MEDIA_ADJUST values. Slow media will
generally need lower settings.
Optimum values for MEDIA_ADJUST may be
found by experimentation. Refer to comments
below.
Thermal transfer printers store separate
values for MEDIA_ADJUST in DT and TT
mode, selecting the appropriate value
depending on the current print mode.
