ROW OFFSET Shifts the vertical start of print position (0 - 99.99 inches) on the label, where:
00.00 inches Is the Default Setting.
COLUMN Shifts the HORIZONTAL, left-justified start of print position to the right (0-99.99
OFFSET inches), without shifting the LABEL WIDTH termination point to the right, where:
00.00 inches Is the Default Setting.
PRESENT Sets the label stop position (0 - 4.00 inches) past the start of print position upon
DISTANCE output. When subsequent label formats are received, the printer will automatically
back up the label to position it at the start of print position, where:
00.00 inches Is the Default Setting. (Auto Mode)
Notes: (1) When set to zero (0), the printer assumes "Auto Sense Mode" to automatically configure
the positioning requirements of an attached device (i.e., tear bar, cutter, peel & present
mechanism, or present sensor).
(2) When set to a value of 0.01 "Auto Sense Mode" is disabled, but the printer retains a
zero (0) positioning value.
CUSTOM Change the factory adjustment parameters (listed below) to finely and
ADJUSTMENTS independently tune the printer to compensate for slight mechanical differences
sometimes evident if multiple printers share label formats, or to make special label
formatting adjustments, where:
Controls the strobe time (1 - 64) to establish the nominal HEAT setting for
DARKNESS
printhead-specific thermal characteristics, where:
32 Is the Default Setting.
CONTRAST Allows fine-tuning (1 - 64) of the relative print edge (gray) adjustment for print
quality, where:
32 Is the Default Setting.
ROW ADJUST Shifts the vertical start of print position (-100 - 100 dots) to fine-tune the ROW
OFFSET setting, where:
000 Is the Default Setting. (Note that if shifting Row Adjust in the negative direction,
modify the PRESENT ADJUST setting [see below] by the same amount.)
COLUMN Shifts both the horizontal start of print position and the LABEL WIDTH termination
point to the right (0-128 dots) to fine-tune the COLUMN OFFSET setting, where:
ADJUST
000 Is the Default Setting.
PRESENT Adjusts the label stopping position (0 - 128 dots) to fine-tune the PRESENT
ADJUST DISTANCE setting, where:
64 Is the Default Setting.
