Creating Labels Using Internal Batch Software
9. The 4-digit Row Field tells the Printer "how far up" on the label
to print the data. The default value is 00.00 and the maximum
number cannot exceed the maximum label length set in the print
parameters window. Use the bottom left corner as the starting
point for row and column.
For the desired vertical placement of your field, enter a number
not more than four digits followed by the return key. If the
measurement entered is acceptable, the cursor will move to the
COL position. If the measurement selected is too large for the
given space or the capability of the Printer, the 'Number Out Of
Range' message will appear.
Data will need to be re-entered. When specifying measurements,
always measure to the bottom of the field. For example, if using
font 6, the measurement will be to the bottom of the
alphanumeric letters. If using a bar code, the measurement will
be to the bottom of the bar code's human-readable line. If the
bar code being printed does not have a human-readable line,
measure to the bottom of the bars.
When rotating a bar code or alphanumeric field, the row
measurement is specified as the amount of space from the
starting point of the label to the top of the field.
10. The 4-digit column number tells the Printer 'how far over' from
the left edge of the label that data is to be printed. Enter a
number no longer than four digits in this field, then press the
return key. If the measurement is acceptable, the cursor will
move to the type position. If the measurement is too large for
the given space or the capability of the Printer, the 'Number Out
of Range' error message will appear and data will need to be re-
entered. The cursor will then move to the type position.
