Hi,
First of all, thank you for using Labelmaker. I'm sorry to hear you are having a hard time printing your labels.
Let's have a look at different things so that I can investigate further:
1- Can you confirm you are printing it with margins set to "NONE"?
2- Can you check if the scale is 100% when printing and you are using a Letter format for paper size?
3- Have you considered lowering the font size or reducing the amount of text? Labels can only contain a certain amount of characters, when there are more inside them, they will grow and misalign
4- Could you take a picture of the misalignment you noticed?
Let me know how it goes,
All the best,
Lucy
