^FM

^FM

The
^FM
 command allows you to control the placement of bar code symbols.

Multiple Field Origin Locations

It designates field locations for the PDF417 (
^B7
) and MicroPDF417 (
^BF
) bar codes when the structured append capabilities are used. This allows printing multiple bar codes from the same set of text information.
The structured append capability is a way of extending the text printing capacity of both bar codes. If a string extends beyond what the data limitations of the bar code are, it can be printed as a series: 1 of 3, 2 of 3, 3 of 3. Scanners read the information and reconcile it into the original, unsegmented text.
The
^FM
 command triggers multiple bar code printing on the same label with
^B7
 and
^BF
 only. When used with any other commands, it is ignored.
Format:
^FMx1,y1,x2,y2,...
Parameters
Details
x1 =
 x-axis location of first symbol (in dots)
Values:
0
 to
32000
e =
 exclude this bar code from printing
Default:
 a value must be specified a value must be specified
y1 =
 y-axis location of first symbol (in dots)
Values:
0
 to
32000
e =
 exclude this bar code from printing
Default:
 a value must be specified
x2 =
 x-axis location of second symbol (in dots)
Values:
0
 to
32000
e =
 exclude this bar code from printing
Default:
 a value must be specified
y2 =
 y-axis location of second symbol (in dots)
Values:
0
 to
32000
e =
 exclude this bar code from printing
Default:
 a value must be specified
… =
 continuation of X,Y pairs
Maximum number of pairs:
60
Example:
 This example shows you how to generate three bar codes with the text “Zebra Technologies Corporation strives to be…” would need to be repeated seven times, which includes 2870 characters of data (including spaces) between
^FD
 and
^FS
:
1
The ellipse is not part of the code. It indicates that the text needs to be repeated seven times, as mentioned in the example description.
Example:
 This example assumes a maximum of three bar codes, with bar code 2 of 3 omitted:
Comments:
 Subsequent bar codes print once the data limitations of the previous bar code have been exceeded. For example, bar code 2 of 3 prints once 1 of 3 has reached the maximum amount of data it can hold. Specifying three fields does not ensure that three bar codes print; enough field data to fill three bar code fields has to be provided.
The number of the
x,y
 pairs can exceed the number of bar codes generated. However, if too few are designated, no symbols print.
