Generated QR code missing first 2 characters

Hi All,

We are using the ZD500 to produce QR codes based on a long string, starting with an ampersand.

When we generate the code from the variable data on our devices, the first two digits are cut from the code (in this case "&T").

When we use the print designer and print from a preview with manually entered code, or drop the string into a text field, we don't seem to have the problem.

Has anyone else experienced anything similar (we are printing from an iOS device).

Cheers,

Stew
