What is the Avery equivalent #?

The OL996WX is not compatible with an Avery item. However, it is the same size and layout as Office Depot's 7500653 and 9512156, as well as Uline's S-19643 and S-21914. We also offer our own software and templates available on the product page under "Blank Templates." These options include Microsoft Word, a PDF template, and our Maestro Label Designer.

To print sequential numbers, you'll need to set up a data list and utilize our mail merge tool in Maestro Label Designer. Here's a brief overview of how to get started using the mail merge tool in Maestro Label Designer: With your label open, hover over "Tools" in the blue navigation bar and click "Mail Merge." Choose whether you want to add a new data list or use one you've previously uploaded. Use the green arrows to add mail merge fields to your design and hit the blue "Add To Design" button to continue to your canvas. From there, you can edit the text by clicking on the "Edit Text" link under your textbox and use the black "Mail Merge Options" button to access additional functionality. You can change the physical properties of your text as you normally would using the left toolbar.

Is it possible to print in the margins of these label sheets? I want to print a barcode in the margin for each label.

The Maestro Label Designer and Microsoft Word will not allow you to print any information in the margins. If you have access to a PDF editing software like Adobe Photoshop or Adobe Illustrator, you can use our PDF template to add barcodes to the margins of the template. Please note that your printer may have non-printable margins which could cause a portion of the barcode to be unprinted. You can visit the link below to download the PDF template for testing with your printer. https://www.onlinelabels.com/Templates/OL996-template-pdf.htm
