Reorder QR sheets

[CJ-Wright]

It might be easier to work with the QR sheets if the ordering is:

|123|456|789|
|123|456|789|
|123|456|789|
|abc|efg|hij|
.
.
.

That way we can cut vertically for each set then cut horizontally in bulk giving strips of a single number where the users don't need to cut the label to get a single QR.

This is a good idea
