Chapter 3 Handling Setting the label size and paper layout for borderless printing This section describes the concepts and settings methods for using Epson printer drivers to perform borderless printing. With borderless printing, the print may extend onto the backing paper (liner) depending on the actual print position and position the paper is loaded. When handling printed paper (labels), take extra care to prevent your hands or the paper from being smudged with ink. Borderless Printing Concepts Printing larger than the label size achieves borderless label printing. Please use media with a matrix to prevent the ink for the section extending from the label from adhering to the backing paper.  If you use die-cut labels without waste surrounding the labels, ink may cause the label and your hands to be smudged with ink, or may adhere to the inside of the printer and cause malfunctions.  Due to the printer structure, a slight margin may remain at the top or bottom edge even if the length of the media layout label is the same length as the label. The following preparation and settings are necessary to correct this error.  Media layout settings for the printer driver: Extend the printable area. 3  Printer settings: Correct the print start position.  Label paper: Use media with a gap between labels that is 4 mm or more. 151
