As you can see in description of ^BQ command in ZPL Manual document:
there is an only a 'normal' value available for field orientation flag of ^BQ command. It means only a normal orientation of QR Code is supported. It should not be a problem because QR Code is omnidirectional code.
Also you missed N flag for ^BQ command. It needs to be used as shown in documentation this way:
You can try to use another number instead of 9 to change magnification factor of your QR-Code . Please see possible values on a page 106 of ZPL manual.
