VARIABLE MEDIA_ADJUST
Function Adjusts
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.

VARIABLE MEDIA_ADJUST n
V MEDIA_ADJUST n
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.
Comments
This command is not supported in DLX or CSeries
printers.
