The SLP650 Smart Label Printer prints dramatically faster than all previous models, up to almost 4 inches per second, providing you with everything you need to print crisp, clear and legible labels easily at 300 DPI resolution, one or many at a time. With highly reliable direct thermal technology, you have no ink, toner, ribbon or complicated software and label sheets to mess with. Plug the SLP650 into your Windows PC or Mac, connect to the built-in USB and you\'re ready to print labels up to 2-1/8\" wide and 7\" long. Replacing rolls and changing labels could not be easier with the new front end drop and load design. The SLP650 supports the SLP-TRAY accessory to accommodate extra large capacity label rolls for extra big labeling jobs.
