I'm sorry to hear about the issue that you're experiencing. We'll do everything we can to assist. Based on your description it sounds like you may be dealing with an issue related to your printer's non-printable margins. Every printer on the market today has a fixed, maximum printable area. The area between where the ink or toner stops and the edge of the sheet is called the "non-printable margins."
Non-printable margins exist to protect the mechanical parts inside of the printer. Essentially, the printer is limiting the range of the ink or toner to keep it from getting into areas of the printer that could potentially cause mechanical failure. This non-printable area is almost always fixed and not adjustable. This can cause the white line appearing when attempting to print labels with very narrow margins on the left/right or top/bottom of the sheet.
We have a tool available that allows you to measure the non-printable margins for your specific printer model. You can access the tool at the link below:

Unfortunately, there isn't an adjustment that can be made as it is a limitation of the printer model itself. Most customer's choose to find a similar sized label with larger margins that will account for the non-printable margins of their specific printer model.
If non-printable margins aren't the issue, our printer alignment guide has a number of suggestions that should improve alignment when printing your labels. You can view the printer alignment guide at the link below:
