Every printer on the market has a fixed, maximum printable area where the ink or toner stops. That space is called the "non-printable margin."
If your label configuration extends to the edge of your sheet or close to it, we recommend figuring out your non-printable margins. To determine what your printer's non-printable margins are, you can look to your printer's instruction manual or use our printer margin tool. Print the document and measure the 1" line in step 2. If the line is not an accurate inch, return to the print dialog box and select the "Fit to Page" or "Print Actual Size" option. Setting the "Custom Scale" option to 100% will produce the same results. Print the document again and remeasure. Once you're sure it's printing to scale, start from the edge of the paper and work your way in until you find the first full box. The numbers next to the first full box are your non-printable margins.
Use those measurements to adjust your label design. If you're using Maestro Label Designer, hover over the "Print" menu and click "Page Setup." From there, you can adjust your settings to fit within your printable dimensions.
