Question about Brother QL-800

Well, I regularly print webstamps from post.ch with it.
However, the matching layout suggested by the post website is a bit of a waste of space on the label. However, the pdf from Swiss Post can be printed on the printer without any problems.

I assume the same applies to parcel labels.

I use a 62mm continuous label roll ... also "grumbles" with me ... but the ticks and clicks in the right place in the print settings ... then it works.

The Post proposal is probably intended to accommodate the address(es) in addition to the stamp ... hence the oversized format.
