If you're wondering whether it's possible to print 4 labels in one single page the answer is: yes, you can! 🙌
You can choose this option once you're in the Print Preview of the PDF document.
From there, you can select how many pages per sheet you'd like to print (in this case, 4 A6 in one A4).
And then proceed with the print as usual.
📌 Please note that label formats depend on each carrier's settings.
