Exercise 3: Bar Codes — ^B3 Code 39 Barcode

Write the following format and send to the printer:
^XA ^FO50,50^B3N,N,100,Y,N^FD123456^FS ^XZ
Try changing each of the parameters in the
^B3
string so you can see the effects.
^B3o,e,h,f,g ^BY
For valid parameter choices, see ^B3.
Insert the
^BY
command just before the
^B3
to see how the narrow bar width can be altered.
^FO50,50^BY2^B3..etc ^BYx
Acceptable values for x are 1 through 10
Alter the ratio of the narrow to wide bar.
^FO50,50^BY2,3^B3..etc ^BY2,x
Acceptable values for x are 2.1 through 3 in .1 increments
Print out a
^B3
bar code with the interpretation line on top of the bar code and the bar code rotated 90 degrees.
Add a
^PQ
just before the
^XZ
to print several labels.
^PQ4 ^XZ ^PR Print rate (in inches per second)
Add a
^PR
command after the
^XA
at the beginning of the format to change the print rate (print speed).
^XA ^PR4
then try
^PR6
.
^PRx
acceptable values for x are 2 through 12 (check printer specs)
See how the print speed affects the print quality of the bar code. You may need to increase the printer darkness setting at higher print speeds.
