ZPL QR code not printing what is in the string

问题

I've got the following ZPL code which prints a QR code with fielddata X50X-8091X-11111.

^XA^PON^FWN^FO30,10^BQN,2,6^FDx50x-8091x-12345^FS^XZ

But what the scanner scans from the QR code is this: 0X8091X11111. So the first X50 is not printed.

What can I do?

回答1:

The ZPL manual has a very detailed explanation of the data switches for QR codes: ^BQ Command Edit: Sorry @Veve, the explination is VERY long. Here is the simplified explination:

回答2:

The chars immediately following ^FD are switches (as defined here)

So you can use something like this;

^XA^FO100,100^BQN,2,4^FD   x50x-8091x-12345^FS^XZ

or this;

^XA^FO100,100^BQN,2,4^FDHM,A x50x-8091x-12345^FS^XZ
