Zebra ZPL Commands to resize barcode to sit within a label

Question

I am using Zebra GT800 label printer with a label role size with 2.5' * 1.75'. I'm struggling to get it resize to the label within, using ZPL commands. I tried with several values in bold text which I read in the user guide of ZPL, but no success.

When values BY2 is used, what it happens is bar-code is getting out of the margins of the label. When I uses value BY1 it is too small to read though. Below with the ZPL Commands used.

^XA^FO150,100^**BY1**^BC,100,Y,N,N^FD00V11636000032562050^FS^XZ 

^XA^FO150,100^**BY2**^BC,100,Y,N,N^FD00V11636000032562050^FS^XZ 

Answer 1

What I would suggest is the following:

1. Continue using ^BY2 to set the module width for the barcode so that the scanners in question can read them.

2. For your ^BC command, set the 6th parameter (the "mode" parameter) to A to set the mode of the Code 128 barcode to "Automatic." Doing this will tell the printer to analyze the data being encoded and will determine the best packing method. This can help automatically compress the printed barcode if the data is compressable (four or more numeric digits in a row will cause a shift to subset C which will help you here).

Example:

^XA^FO150,100^BY2^BC,100,Y,N,N,A^FD00V11636000032562050^FS^XZ

Try this:

^XA^PRA^BY1,2^LH000,000^PQ1
