Jagged barcode from browser

[InsaneSuperSand]

Hi! I have Dymo labelmanager 280 and I tried to print the barcode. But when I do it from the browser, straight from Snipe, the printer prints a jagged barcode. You can see it in the picture.

This problem does not appear when I save the barcode on the disk and print it via printer soft, or OS. But then I don't have the rest of the label, like serial number, etc.
It was tested on Windows 10/11 and macOS. On Chrome, Firefox, and Safari.

Do you have some solution or trick how to fix it?
