Half of the labels do not print from the printer. Those that were in the box did not have this problem.

Aside from the printing issue, it was noticed that towards the middle of the roll, the labels were poorly glued, resulting in the machine cutting them, causing half of the sticker to turn inside, stick to the blade, and create a feeding problem. (Besides the hassle of cleaning the blade afterward)
In my opinion, it is better to buy original labels that are a little more expensive and work properly (if there is not a huge workload—because there we are talking about professional machines like Zebra anyway) rather than no-name ones that cost you more than the waste you have.
